Oh wow... I had my gall bladder removed early last year after I lost over 40kgs since 2009 after a gastric sleeve operation. I went from 108kg down to a healthy 67kg.
I went off BC November last year. Had irregular cycles. Finally got a dr to listen to me and send me for tests. Diagnosed PCOS mid this year. I was put on metformin straight up and provera to regulate my cycles to see if my body would ov by itself. It didn't. I was so sick on the metformin it was starting to affect my work so OBGYN took me off it.
I was then put on clomid for 3 cycles, 50mg, 150mg and 200mg - all never made me ovulate (and never had side effects). I had ovarian drilling, HsG test done to check my patency, as well as my uterine lining scraped all done together early October.
Saw my OBGYN last week for a follow up consult and as my period started by itself after 50 days (it never did when on the clomid - I needed provera every time), he said to get bloods on CD23 (next Friday) to check if the drilling has had a positive effect on me. If no ov this time around, then I will be put back on more fertility drugs. Currently on CD14 today.
