If you got a positive OPK today, you will ovulate within 24-36 hours. So as long as your DH's sperm count isn't low, go ahead and do today, tomorrow and the next day, and maybe even the day after that just to be sure. If his count is low. I would do it now, and then not tomorrow but the day after tomorrow. You should do every other day if he has a low count. So, go do it now and then do it Saturday morning if there's an issue on his end.
