Please help (FTM)

I’ve been getting really bad pains in my stomach for the past 20 minutes. It’ll come and then stop. And then happen again a few minutes later.

I’m scared because I was told I could be at risk for premature labor because my placenta vessels are restricted.

I really don’t know what a contraction even feels like. I doubt it’s labor because I have not lost my mucus plug or anything like that.

I’m 25 weeks.
