I noticed this too. I get cramps right after I climax. Unfortunately, hubby hasn't gotten too much action lately. I'm trying but haven't been in the mood this entire trimester.
Yes, I've had unusual pains down below after sex a few times with this pregnancy. More like sharp pains in my vaginal area and dull cramping. My doc said everything is more sensitive during pregnancy, so unless the pain is severe, it can be normal to feel some discomfort that you wouldn't feel otherwise.
