This is my second pregnancy and first time I've ever carried twins. I started showing before 3 months with my son 6yrs ago. When should I expect to start showing with the twins?. I get bloated at night but the belly disappears by morning. I've had a lot of morning sickness so food hasn't really been my friend I lost 2lbs between 6weeks and 10 weeks. Dr. doesn't seem to be concerned and she said they are measuring up to date and they both have strong heart beats at 164 and my bp is perfect. I'm not a heavy woman, I'm fairly fit. I guess I kinda figured since there were two i'd be showing a little already. Anyone not showing and thought you would be by now.
