Contractions?

I'm 31 weeks, 1 day. I have a bad case of anxiety, so bear with me.

I've been having low back pain that comes and goes for the last 24 hours. It varies in intensity, but doesn't stop. It feels like pms back pain. I have some tightening in my belly, but not as constantly.

I'm terrified that if I go into l&d I'm going to look stupid and nothing is going to be wrong.

What would you do?

Mind you, I know it's stupid to be that worried about looking silly. But i can't help it. I've been crying just thinking about it. And my husband said he thinks I'm over thinking it, which did not help.
