I totally know that feeling. After awhile, DH and I felt like timing sex was such a chore and it was starting to become more work trying to figure out fertile time and became less fun. We finally just said "forget it!" and just BD when we wanted to. Maybe that's why it happened for us... We only BD like once around the cycle we got pregnant and I really think it was because our mentality about the whole thing just changed. I'm not saying we gave up, we just literally stopped obsessing about it. And maybe DH had to build up sperm or something. We never got him tested but I think about that sometimes... xoxoxox
