Hip pain

Rachel EDD 1/20/20

I’ve been having achy painful hips (mostly on one side) tonight that seem to radiate sort of into feeling like cramps. I know there’s a lot of discomfort in pregnancy. This has me worried. I paged the on call at my doctor but she never called back. It’s not too bad. Probably 3-4/10 on a pain scale. I don’t think it’s anything I did. Anyone experience this or know if it’s ok?
