Feel like abdomen is at max capacity and only 24 weeks

I often feel like I am as expanded and pressurized as can be and I’m barely over half way. my skin is stretched & my abs feel hard and stretched to the max & will pull if I twist to one side or the other. I was wondering if others feel like that and if you just continue to expand somehow.

I was thinking it could be my IBS causing a lot of bloating and swelling that is adding to the pressure. Have been having a lot of acid reflux too. (Both of these were issues before pregnancy). I’m on the upper range of normal weight gain (went from 5’6” 122 lbs to 142 lbs) but nothing crazy. They also said the baby was in the 90th percentile of size at the 20 week scan. My husband comes from big babies (10-12 lbs for all his siblings and no gestational diabetes) so maybe it’s just because the baby is big?

Anyway, I figured the pressure and stiffness was normal but at my 24 week appointment I was asked to schedule another appointment within a week so they could re-measure because they were surprised at the size from pubis to top of uterus (should have been 24 to 26 inches and was 28 inches).

So, does everyone feel this way? & if so how can it take any more pressure? anyone else with IBS & did that make you larger and more swollen in the abdomen?

Thanks!
