Hi all, I am TTC from 1.5 yrs and am diagnosed with unexplained primary infertility.All my reports are fine and so are DH reports. It so happens that in some of my cycles when there is a period delay, scan shows a cyst in one of the ovaries. Then I am put on Femilon and the treatment starts when I am on D3 of my period. I was wondering if this is normal and what is the difference between this and PCOS. Any friends who have gone through this and conceived? Please help!
