Hi M.. You can also look back a few pages and see my post on this same topic back in December. I got pregnant with my son the first month we tried, so I thought the second would go just as easily. About 4 months into it is when I posted here, turns out I was pregnant at the time! What I did doesn't leave much room for romance, but it should cut your time down. You have to know when you are ovulating! My cycle changed after I had my son and when I actually started to track from the first day of my period to the first day of my next period, it was always changing. One month it would be 25 days, the next it was 29. Four days changes the window in which you should be trying a lot. I went to ivillage.com and signed up for the free two month fertility planner. You really have to play with it and read about it to make sure you understand all the settings. It will actually give you your fertile window and if you track your waking temp. it will also give you your day of ovulation. That brings me to the next step, buy a basal thermometer for $8. I got mine online but I think CVS has them too. After you start your cycle, you take your waking temp before you get out of bed every morning. The form that comes with the thermometer will explain it, but you will see a temperature spike on the day of or before you ovulate and it really works! My temp for a week was like 94.1 and one morning it was 97.9! I also bought the ovulation test strips you can get everywhere and used those every morning as well. The morning my temp spiked, the test strip came out positive. This means you should be spending some time with you hubby that day and the next 2-3 days. The first month I tried all this, I was amazed the stuff actually worked and I am due at the end of August! You could probably just use the temp, the test strips probably aren't necessary. the fertility planner was cool though, I would definately use that.
It turns out that I just was not calculating my fertile days correctly because my cycle was always changing by a few days. Good luck and let us know!!
