Has anyone had this happen? I'm in so much pain and I'm wondering if that could be the reason. What does it feel like? Hubs and I BD and after that I had the worst cramps, not like af cramps, but different in a way. I'm 6 dpo and I don't think it's implantation cramps, this spread from my right ovary, through my hip and into my lower back as soon as we got done. Never felt anything like it before.
