I dont O on my own and due to this my cycles are all over the place.The thing is,when you dont O,your body doesnt really know when to bleed kwim? So your cycles get crazy and unreliable.
In my case,my body tries to O a few times throughout my cycle,but in the end nothing happens,so my cycles last anywhere from 17 to 50+ days,and in the end I get what my OB reffers to as "break through bleeding".
I never know when AF is coming which is why my OB has allowed me to take Clomid

Im hoping it works!!!
