In a second time mom, and I don't wany to sound stupid, but is it normal to be crampung and hurting at 33 weeks and some days? My lower back is cramping, like period cramps just a little more intense, and around into my lower belly. I took a warm bath and it helped while I was in it *getting in and out caused sharp pains in my vagina* but once I got out the cramps returned. Its also not a coming and going cramp, it is consistent. Should I worry? Or is it just normal pregnancy aches and pains?

*also it's NOT accompanied by any spotting or bleeding*
