I'm having really bad pains in my tummy..kinda like stretching and hunger pains, but I have already ate....

round ligiment pains. baby #2 almost 18 weeks.

I don't remember what this feeling is from my first!

should I go in? I'm at risk for perterm labor, I take a shot every week to prevent my cervix from thinning to early. also high risk because I got pregnant when my son was a month old...
