Real or fake contractions, 33 weeks

Hello ladies. So, I’ve regularly been having lower abdominal pain which feels like menstrual cramping, nothing too bad, I’ve told my dr. And she said there’s nothing to worry about.

Well last night my fiancé ended up having sex (excuse the tmi) and we got done having sex around 10-10:30. Ever since then I’ve been having the menstrual like cramping. I feel it coming on in my lower back and works around to the front. They aren’t excruciating but I do have to stop and breathe through them. I decided to time a few of them and this is what I got...Do you think I should go to the hospital? Or do you think they will eventually stop?
