BH Contractions after sex!

So me and my SO had sex maybe 30 mins ago and I keep getting Bh contractions... they don’t hurt, my belly is just VERY tight. And the baby is still moving a lot. I looked it up and it read it was normal. But I’m so scared I’m gonna be at risk for preterm labor 😟 I’ve had 2 premies at 32 weeks. I’m 25 weeks today! I reallllllyy want to go full term this time. Should I stop having sex ???
