I didn't know I was pregnant until I was 7 weeks and was having sex then. I've done it all throughout the first trimester and baby is doing great! If it hurts, I recommend stopping, but it won't hurt baby!
Lol ok just wanted to make sure didn't want to harm the baby. Was told your first trimester is where your baby is most delicate and you have to be careful what you do.
As long as your doctor didn't say otherwise, then its fine! :)
