I just entered my second trimester, I'll wait a few weeks before, I try to have sex again. I don't want anything to go wrong.
I had spotting from having sex in my first trimester.. when I went to the doctor he said it was normal as long as it wasn't heavy or lasted more than a few days.. but he also told me not to have sex till my second trimester just to be sure the baby stays safe. Because a lot of girls miscarriage during the first trimester.
As long as you aren't bleeding enough to fill up a pad or pushing clots you should be fine. I bled with my first when I we would have fun after, it wasn't a lot, but I did have very light spotting
