Orgasm and semen can trigger contractions. Even when not pregnant, there's times I've had to have a bath to ease a cramp after sex.
Female orgasms causes minor uterine contractions, but it's usually not contraindicated. But if your dr told you not to have sex, you may want to talk to the dr to hear the full explanation as to why you, specifically, shouldn't. That would probably motivate you to follow instructions.
I would say listen 2 ur doc. My hubby & I hvent been able 2 have intercourse which has been pure & utter torture 4 both of us. I have a cervical cerclage, so if we tried my hubby penis would get cut up from my stitches. Any who we have resorted to a lot of 4 play & alternatives, but my doc made it very clear that I could not have orgasms. He said bcuz I'm high risk it could cause contractions that could cause me 2 have pre term labor or a miscarriage.
Wow! Thanks for the responses, it was all very informative. I do plan on speaking to my Dr in regards to this I was curious as if I was being a brat. :/ ... But now that I've read I'm sure to follow orders. But gosh it's been so hard- I even have dreams of DH and I, luckily no orgasm. @YoungLadyDay14 your situation seems a lot worse than mine. I hope everything goes well. ;)
