tummy size

Stephanie
This is first thing in the morning yesterday at 13weeks. I see so many women posting their bumps. I worry mine is too small. I look severely bloated I think. Last appt I had was 10w1d and everything looked great they said and heartbeat was 188BPM. I go back on exactly 15 weeks for check up and they'll listen to heart beat with Doppler I was told. Then ultrasound 4 weeks after for gender reveal. The other night I felt "bubbles" in there for a couple min. Husband listened and said he could hear it too. I haven't felt it since. I don't know just think I should be bigger? I've gained almost 7 pounds.
