First clomid cycle. Questions!

Sara
So prior to clomid my cycles have been very irregular/long and my OPK's have been negative/false and very late. So, given that I'm on clomid to make me ovulate, do you think realistically my fertile window would be this week? So far my OPK's are negative. I took clomid day 3-7 and I begin progesterone day 17. We are doing the every other day method. Thoughts?
