31 weeks....anyone else in pain?

DeBa

just beginning today..experiencing a ton of lower back pain (pretty well in my butt), and painful cramping...feels like.painful menstural cramps. ive experienced braxton hicks before which were not painful to me, just uncomfortable, so im a bit concerned. is this normal? its not excrutiating pain, but its enough. i dont remember this with my first pregnancy. im 31 weeks and 2 days
