PLEASE EXCUSE ME IF THIS IS THE WRONG FORUM!!!!  Hi, me and the other half are TTC and I am AF due in 5 days.  I keep feeling some weird symptoms but have a few health problems so just could be a symptom of those.  I don't feel pregnant, but a friend of mine who just had a baby said she knew she was pregnant Before the test became positive....  so to all of you who have been preggers before... did you know?  Did you feel pregnant?  I'm so curious!
