Stretchy days

Anyone else have days where they feel like their belly may just split right open? Some days i feel good and normal, just big. Other days i feel like my whole stomach aches and is super sore. I already have pelvic girdle pain to top it off. The stretchy days i can barely walk or turn over in bed. I'm only 24 weeks. I wonder what kind of fresh hell the third trimester will bring? I've mentioned this to other veteran moms but of course i get the classic "oh just wait" line that they use for everything....not really any helpful feedback. Lol
