Gas or preterm labor pain.... HELP

Emily • Momma to Miss Emma!

I'm 31w2d and I've been having some issues that lead them to believe I won't make it to 40 weeks but we are just waiting to see what happens. Yesterday I started having random pains like period cramps but they didn't stick around. Today I have been having pain up in my ribs and around my upper belly, made worse with movement. It seems pretty constant though. I believe baby dropped a couple days ago but she is still active. I took some gas medicine to see if it lets up and if not I guess I'll be calling my doctor tomorrow... any advice or similar experiences?!
