It's our first cycle TTC and I just got a positive OPK this afternoon. Problem is DH left town this morning and last night was our last BD. We BDed lots the days before that too, but I'm out of chances now. Is there any chance I could still get a this cycle? I've read conflicting info on how long sperm last (and obviously it varies as well). I really want to get that , but part of me thinks I've missed out this cycle and I should go drink a big glass of wine, but too scared just in case.
