Take it slow. How many weeks are u?
Its completely fine. My doctor said so. Its just your body or well stomach adjusting
Tht has happened to me as well i just took a break I'm 23wks and I'm pretty sure it was because we were being a lil ruff so just take it nice and slow and also what i hate is when you do have an orgasm your uterus tightens and contracts and feels like its hugging the baby
Unless u have bleeding u should be good. Just take it slow. Im 35 wks and still get cramping afterwards. Just drink water and lay down when ur finished
I Also Heard Having Sex While Being Pregnant, Could Be REALLY Painful!
