okay here we go

help me out ladies! I started this pregnancy out at 269 the heaviest I have ever been. I lost 10 lbs my 1st trimester and my 2nd and 3rd trimester and I've been at a standstill and havnt gained anything. I'm at 259 and can't seem to gain anything! I'm wondering if the baby is growing off of the weight I already had! my belly is growing I just worry lol!
