Two women I know say that they knew almost immediately that they had conceived

For some woman who have been tracking their temps over a matter of months and watch them closly they can see that the temp stays up and that is a sign of Pregnancy.

From the time of the missed period to about two weeks after that, the time of missed OV I guess, I get extreme hot & cold flashes and confusion.  Like I change my order in a restaurant twice and then decide not to eat.  (Very fun for hubby, who at that point just thinks I have PMS). I also get EXTREME insomnia from missed OV til, well, til about 8 weeks, when it's replaced with exhaustion.  Also fun for DH. I also get a pain in my side, on & off.

A lot of old wives' tales and a lot of old wives, period, can pick out a woman the minute she catches pregnant.  I know my mother (who had five children of her own, four of those in a three year period) knew I had been ttc and picked me out as pregnant about three days after I ovulated (long before any hCG workup happened or was possible). I A lot of people tell me they can do that, but they never knew about me.  And we don't tell for 3 months. Tara Sent via Deja.com http://www.deja.com/ Before you buy.
