This is embarrassing but I want to understand boundaries. I am in second trimester and normal so far, but sometimes things get a little intense and then I worry. Did your doctor mention what to avoid?
Intimacy in pregnancy is normal but gentle is the way, no rough handling. Your comfort comes first now. If you feel any pain or bleeding after, dont ignore it, call your doctor. And honestly just talk openly with your gynac, they answer these things without judging.
For a normal healthy pregnancy gentle intimacy is usually fine, but rough is best avoided, take it slow and comfortable. If you've had any bleeding, pain, or a high risk pregnancy your doctor may advise to hold off. Honestly it's worth a quiet word with your gynac about what's okay for you.
I'd really say keep it gentle and check with your doctor first. I had complications so I was told no intimacy at certain times. If your pregnancy is high risk or you've had any bleeding or cramping, please ask your gynac before, dont take chances with rough stuff.
Be gentle is my honest advice. In a normal pregnancy sex is allowed but not rough, your body is doing a lot already. Listen to what feels comfortable, stop if anything hurts or you spot after. And if your doctor told you to avoid it for any reason, follow that.
