Just chiming in...as for timing, we had our one attempt approx 15 hours after first +OPK. Basically it was positive early in the am and we dtd later that evening and i'm currently pregnant with a girl. I was on a strict LE diet, husband did FR for 10-11 days leading up and we incorporated suppliments. i believe diet and lowering sperm count were the major factors for me personally(not necessarily timing). Good luck!
