I am on CD 27 of an irregular cycle. My <a href="https://play.google.com/store/apps/details?id=com.glow.android">fertility apps</a> are predicting different start dates for AF but generally between CD 30-33.

This would be my 9th cycle of TTC. I took Femara/Letrozole cd 3-7. My ob said I would produce false positives on OPK so I don't really have any idea when I ovulated. I have had sex every day or every other since CD 6. However; I slowed down a few times around CD 20+...now my Ovia app has changed my "fertile week" so I have no idea if I did the right thing..I have been cramping for about 3+ days now and had some creamy cm a few days ago. I'm so terrified AF is coming..I almost don't want to test. Sorry this is so long. Has anyone ever cramped a lot this late in your cycle and had a BFP?
