My partner and I are TTC using a known donor. I have PCOS and I've been trying to ovulate for about a year and this month it has happened! Definitively. I'm just not sure which date. When I set Fertility Friend to Fertility Awareness method it tells me that I ovulated on Day 16, which is what I had originally thought and what my acupuncturist thought as well. I tried on Monday a well because I just wasn't positive and my EWCM was throwing me off. I've been treating CD16 as O day and looking at that second temp rise as a triphasic shift. However, today, just because I'm compulsive and the TWW kills me I switched my charts to the FF Advanced method and it changed my O date completely to day 19. This is in line with my EWCM but I just am not sure what to think. Either way I got at least one try in so I hope I'm in the running but we'll see. Any insight you alll have would be awesome. Thanks!
