Where do I get a more accurate pregnancy test?

I suspect that I'm pregnant for a whole lot of reasons but none of the 6 pregnancy tests that I've taken has turned out to be positive. Are there any tests that work better than others or is there a better time to expect the best outcome? My period is now 5 days late.

What can I do next?

Summary

There are many different in home pregnancy tests in the market, but if you want an accurate pregnancy test, consult with your health professional.

So What Happened?

Thanks to everyone for your advice and information. I got my period all of a sudden this morning (didn't creep up on me like it usually does) exactly 1 week late and it's been a mess and lots of pain and nausea. I think that I was pregnant but that it wasn't a viable pregnancy and now I am actually experiencing a miscarriage. I knew something strange was going on so it was helpful to have the input from you guys. I appreciate all of your help, thanks again!

If you do not excrete very much hCg, you will not test positive by any means at this early date. Some women won't test positive until into the 2nd trimester.

If you suspect you're pregnant, behave as if you are -- for the safety of the baby, or any other reason that may have a time-critical factor.

There is nothing to lose by being extra healthy... or making appointments to do screening or whatever asap.

I gotta say I'm 100% with Lacy. I took a pregnancy test with my first son and it came back negative, I threw it away. When I was cleaning the bathroom the next day, it fell out of the trash and it was positive! I went to the store and bought another one and once again, it was negative. I looked at it a few hours later, it was positive. The urine tests are all the same... they measure the hcg in your urine. Each woman produces higher amounts at different stages. All of the home pregnancy tests are the same; name brand or off brand. They even measure right up with the ones that they will give you in the hospital. I would call the doctor and ask for a blood test. They are more accurate than the urine.

Not to criticize, but Lacy is wrong. They are not all the same. They all have different sensitivities to the hormone your body produces while you're pregnant. Generally the more expensive ones are more sensitive. It's one of the few things in life where you do get what you pay for. You can go to planned parenthood or or any organization along those lines and get a free pregnancy test done if you can't afford to keep testing. But, your best bet is to go to your doctor and ask for a blood test. Over the counter tests don't touch the sensitivity levels of a blood test. Good luck.
I have been told that I am wrong, but I am positive I am not. And just want to make things clear. Here is a quote from a reputable website, google "are all pregnancy tests equal" or something to that nature and you'll find out the same thing.

"Not all pregnancy tests are created equal. The more sensitive the test (the smaller amount of hCG it can detect), the earlier the opportunity to detect pregnancy. That means with a test sensitive to 20 mIU/ml hCG, a home pregnancy test is accurate as early as six to eight days after conception, well before your first missed period. NOTE: Conception may take place several days after date of intercourse, so the date of intercourse should not necessarily be viewed as the day of conception.

Also, a pregnancy test will turn positive after leaving it for a few hours even if you're not pregnant. The reading is only accurate at the time the instructions tell you to read the result. If you wait hours after, it is a false positive.

I am not trying to be "rude" as I am told I am being by stating that other people are incorrect. I am simply making sure that the truth is known.

**Hey Ashley...what isn't clear about 'in my experience'? BTW...Once you miss a period, they are the same across the board. OTC urine tests work completely different than Serum tests.**

In my experience they all work about the same. I will tell you my story though; we were trying to get pg and I was sure that I was, but the test said no...so we went off to church and our morning activities. Upon returning home, the test lying in the trash caught my eye...it was POSITIVE! Knowing that you aren't supposed to trust the result after a certain amount of time, I took another a day later....same thing negative at first...positive later! Anyway...that negative pregnancy test was born 9 months later!!

With my first pregnancy, I knew I had to be pregnant, but it wasn't until 8 tests and two weeks after I missed my period that it finally came back positive (and even then the line was sooooo faint I could hardly see it). I'd say try the new EPT digital...it actually spells it right out for you!

Double check your tests. I had that with the first one I did for my second pregnancy. It showed negative, but a day or so later it was showing positive. Sometimes different tests will do that. If you're still not sure, go to your doc.

I found the First Response test to be great...It showed a faint line 3-4 days before my period was late. With my first pregnancy though, I suspected I was pregnant but did not get a positive test until I was about 6 weeks along. Not sure why it was different this 2nd time, but apparently I didn't have enough of the hormone earlier on the 1st time. Good luck!

The best way to find out is go to the doctor and get a blood test. I was sure I was pregnant, I had been throwing up for 8 days and we were trying. I went to the doctor, did a blood test and it came back negative. But I didn't have the flu or anything other "sick" symptoms. Well, 2 weeks later I did another blood test and sure enough I was pregnant. It might just be too early. I know someone who never had a positive at home urine test during her entire pregnancy, even when she was 8 months pregnant. The first urine of the morning is supposed to have the most hormones in it, so you can try that if you haven't already. But like most people have said, the best way to find out is to get a blood test from a doctor.

First off, you likely ovulated later than you thought, you didn't have a miscarriage. It is extremely rare for a woman not to get a positive on a pregnancy test at the time her period is due. It all revolves around ovulation. Just because your cycle is a week "late" doesn't mean you are pregnant. In fact the symptoms you were feeling, are from progesterone, that the corpus luteum produces. I have had many miscarriages, you didn't have one. You ovulated later.

J., I had the same thing happen to me when my son was 18 months old. I had all the signs of pregnancy, nausea, breast tenderness, etc. Went to the doctor and had pregnancy test which came back negative. He scheduled an ultrasound and found I had a ovarian cyst. Go to your doctor and find out for sure rather than continueing spending money on pregnancy tests.

I would call a doctor. There is a blood test that works best of all. If you're five days late and not pregnant they may want to see if there is something else going on - especially if there are other reasons that you think you are pregnant.

My positive did not show up until I was 3 1/2 weeks late. The First Response early detection is the most sensitive. You could always call your dr to get a blood test. Also use first morning urine it is the most concentrated.

With my second pregnancy I took about 5 tests in the two weeks after my missed period that said negitive, then one day I took one that was positive. With my third one I took two tests before the third one said positive. I always say a negitive only means you are still waiting to know.

Hello J., It is too soon for the test to be accurate. When I was pregnant for my last child the OBGYN insisted I wasn't pregnant after doing a urine test and an exam. But I insisted, so he took a blood test which was accurate enough to tell how many days along I was. A woman knows her own body if she pays attention, and it sounds like you are intune. Congrats!!

answers from Detroit on

The tests can detect a hormone (often called betas) that is in your system when you are pregnant. The hormone has to be at a certain level, which varies from test to test but I believe the most sensitive test can detect a levet at/above 15 (I could be wrong about the number). Anyway, it takes some time to get to this level - the hormone usually doubles every 48 - 72 hours. You could be taking the tests too early. I don't have a regular period myself so I have no idea when to expect mine, but it the tests say they detect pregnancy 3 days after a missed period and you are regular, I'd guess that you are not pregnant. If they say they detect pregnancy 7 days after a missed period, you are just taking it too early. The other possibility is that you are pregnant but the pregnancy is not viable so your hormone levels are too low to be detected when they should be high enough to be detected. Hope this helps and get get the outcome you are hoping for.

Go to a doctor or ReadyMed and get a Preg test that uses blood.

I'm a Med Tech and I know the Serum Blood test is WAY more sensitive than the urine one. The blood will come down first and being that you are 5 days past, it'll definitely pick it up.
