waited the 6 weeks. got a lot of stitches. something happened, blood was everywhere, but I loved and nothing retore. id recommend the 6 weeks to lower risk of infection and of how extremely fertile you are after you give birth.
I was 2wks PP when I gave in & had sex. It's definitely uncomfortable at first, but if you end up getting stitches, I advise you to edit the 6 wks. I had one stitch and it was a little bit of a pain.
