anyone experience heavy cramping after sex?

Sex was amazing by the way . But as soon as we were don't I had some crazy ass cramps😭😭so bad I couldn't move . They went away after about 10 mins I was so scared. I googled my symptoms and it said that it's not uncommon because organisms can sometimes make the uterus contract. No bleeding and thank good I feel fine now but that was really scary 😱I'm only 6 weeks and 4 days
