Cyclo progynova anyone?

Moks
I was having 17-20 day cycle and my
​Gynae prescribed 3 months of cyclo progynova to regulate my cycle. 1st month, my bbt was in a mess and I felt bloated all the time. This is my
​2nd month and my bbt looks great, but I had less bloating. I had migraine and nausea at around 9dpo and slight cramps every now and then. Today is 14dpo, got a BFN. I thought this could be my month but perhaps the symptoms were just from the progynova pills...
