In May our little boy was born still and ever since my cycles have been all over the place. So I decided to use a OPK for the very for time just to see if I'm still ovulating and when. I started testing on day 14 of my cycle. We were intimate on Thursday, day 19 and later that day I got a positive test and another positive on Friday, day 20. We thought that was enough, we'd been intimate on the day of the first positive test and a positive test means ovulation, right. Today I was reading that ovulation happens 36 hours after the surge or when you can get a positive test not at the start of the surge or when you first get a positive test. So now I'm confused and a little worried we missed our chance this month.
