So- I’m currently on day 36 of my cycle (on bc for over 10 years, got off last sept.- normal cycles of 30 days but super light until January - was given progesterone to jumpstart- “normal” January, February, missed period in March so another round of progesterone, normal in April)

Realized I was taking opk wrong first half of this cycle but bd every other day anyways. Took this opk today and the lines are dark? Anyone have this happen so late in the cycle?
