CD 15 Update

Well, I'm confused. I normally O on CD14-CD15 during natural cycles. I anticipated O this month because I have low pre-O temps. So far, I haven't had a positive OPK, though. Having said that, I had a significant temp dip today. So, now I'm curious if I had a sharp LH surge that I missed and today is O. The reason it matters is that DH has a low count. So, we don't want to overdo it and lower the count even more. Ugh! Decisions, decisions!
