I was barely showing at 20 wks everyoe is different
If its your first pregnancy then its normal,every woman is different.With my first pregnancy i was worried because im petite and at 3 months i seemed to have no belly at all,it wasnt till i was bout five and a half months tht i started to feel my daughter move.With this pregnancy however things have been moving a bit more quickly with my son:) i havent gained much with him either,with my daughter i gained alot of weight towards the end of my second trimester but with him ive only gained 18 lbs so far and ill be in my last trimester in two weeks.My last check up i lost four lbs i thaught tht was bad but my OB didnt seem to think so.Im expected to gain two lbs a week without even trying so as long as i gain at least the 25 mark before he's born,she said thts fine.So dnt worry,never hurts to ask your doc though.
