Tiffanie

Hello! So quick thing about my journey. This is my 2nd month on letrozole (5mg). I never got an oh surge. Some days a little darker but usually be faint. We still BDd every other day during my “fertile week” in case. Well tonight, 1 day after I was supposed to supposed to ovulate, I’m feeling very crampy and achey down there. I also had some milky colored thin discharge today. I took another Opk to be sure but I’m not sure what to think. Pic of my cycle below.
