Yeah, if you don't have symptoms, count your blessings. I started gaining weight right away and was nauseous. What exactly do you mean by "feel" pregnant? Do you mean start to show? Five or six months. Do you mean cravings and morning sickness? Right away.
Youre so lucky, zofran did not work for me. If you are not have morning sickness feel blessed and congratulations
I found out around 5 weeks and didn't have any symptoms until about 7 weeks. I am now 8 week's and 3 days with a touch of morning sickness....zofran works wonders.
