haha, the minute I get pregnant my nose stuffs up, and it doesn't come unstuffed until I give birth. I was So clogged up and was also feeling a tad weird, so thought I had either allergies or the flu. First time I ever went in for allergy testing, my doc routinely asked "Is there any chance you might be pregnant?" and i had to say yes, so before doc prescribed anything for allergies he ran a pregnancy test and... well, hello there, little feller! I never got acute morning sickness... I felt queasy 24 hours a day for my first trimester, but only threw up once. (I suggest you avoid clam dip, from dire experience). And don't forget to start your prenatal multivitamins before you conceive, to give your new passenger the best possible start into life.
If you have a regular 28-day cycle, you'll probably have fairly regular ovulation about halfway between - at about 2 weeks. If your cycle isn't really regular, there are still ways to tell. Ask your ob-gyn - you can check the consistency of your vaginal mucus, plot changes in body temperature, etc. Also look at a book like "our bodies, ourselves" that explains the whole process. I usually get a pain in my ovary at ovulation - for some reason they call it "middelschmerz". Sounds like something you'd find on the bottom of your shoe. Interestingly, my left ovary hurts a lot more than my right ovary. I can usually tell which barrel I'm firing on.
good luck with your new baby!
