It sounds like it could be ov since its on track for it. The only way to rule out potential pregnancy is to take a test. I'm finding more and more that our bodies are a mystery. I have had cycles that weren't as normal and thought that maybe I was pregnant, but it seems it was just a wacky cycle. I can't remember when you first started taking Met, but it could be your body adjusting to it and changing the signs of ov. Also, if you had an abnormal period, it could be your body is still clearing out the old blood that didn't clear out with your period. You have just had a time of all of these wacky cycles, I hope they straighten out soon for you.
