Cramping/pressure after sex while Pregnant

I know some cramping can be normal during pregnancy. Last night I had sex with my husband and afterwards I had some cramping. It was a little uncomfortable. I also had What felt like pressure maybe. Idk it just felt like my vagina was heavy, like my uterus was gonna fall out or something. I’m almost 16 weeks. I woke up this morning feeling better. No cramping. No pressure. I feel flutters so I think the baby is okay. Should I consult with my OB?
