I agree with the pp. You will probably get a true positive within a few hours, probably not longer than a day at most, so I would take another one in about 4-6 hours and get to BDing! Good luck!
I would say it's close but not quite as dark as the control. Not long I'm sure!
I seem to get spotting if OH hits my cervix.
If that was truly a +OPK last night then there is a good chance you will ovulate today so I'd say yes, BD away!
