My period is pretty regular (every 27-29 days). Ovulation usually day 12-14. This month, I wasn't going to do opk, but after my predicted ovulation date, I did. It was negative, never high, then randomly peaked on day 17 (digital test). My period was supposed to come yesterday, day 28, but Glow predicts Saturday because of the late positive opk. Yesterday and today, my discharge has had a pink tint when I wipe, but not every time. I never spot, I just start. Is it too late to be IB and my cycle is being weird, or is there hope??
