sex too soon after delivery!! be careful!

I am not exactly sure where to post this, but here it goes. I just read two posts about women having sex quickly after giving birth. You are very, very fertile after giving you will almost every time get pregnant, so PLEASE BE CAREFUL! Also they don't say wait for 6-8 weeks because of comfort or your stitches, but also because orgasming can cause hemorrhaging!! Also you are very prone to infection! Please think it through before having sex soon after birth.
