I have ben taking ovulation strips because were TTC #2 cycle 4 and im CD 10 right now hoping this is the month and the past few nights my hubby had ben going to bed early (workig 12 hour days) my strips have ben negative but close on, and i say to him tonight, we going to baby make tonight? He says "NOPE, im building it up for you" lol! I had to laugh bc it was so funny! But for realsss how long is too long to wait when ttc for the sperm not to replenish?
