So I have been tracking and noticing that every month when I start my period it is exactly 2 weeks of when I would have ovulated. The reason I know if because I'm getting positives on OPK. And ovulating on the 3rd day. Now this is what's getting to me. I've been told to do EOD to try and conceive and my husband and I have been doing that.. at night only. So I've check my calendars and the day I'm ovulating, that night we BD. So I'm wondering should we have sex for 3 nights straight this coming month? Meaning the day I get a positive opk?
