Did I miss the ovulation window?

Izzi 💍🤰

Hey Ladies,

I'm so confused with my current ovulation schedule, I don't have a thermometer at the moment to use that as another source to test ovulation. On Monday I had low LH, Tuesday I had high fertility and yesterday I was apprantely ovulating, however I thought I wouldn't until today. I BD before taking the test at 22:08 on Wednesday, where it tells me my ovulation was fading.

I BD day 13 and day 15, did I miss my chance? I can't believe I had a fertile window of less then 48 hours. Is this normal, does this happen to you?
