Sounds like a question for your doctor and whether anyone else did or didn't doesn't matter to you... What matters to you is YOUR baby!
Sure people have in the past and it has been fine...
but how far along are you?
How rough? Like a violent rape type rough? Go see a doctor!
No one here can ease your mind like your doctor can and if there is a problem, that's the only one who is gonna help!
Personally, I have not participated in such a thing, nor would I, for the baby could be harmed. If you have, I'd get with you ob/gyn soon to make certain the baby is OK. And, for the baby's sake, please be careful until the pregnancy is over.
