I am so excited right now. Me and my partner have been ttc for just over a year now. My last depo shot ran out September last year and after a year of waiting for my cycle to return I went to the doctors. I had a scan and blood tests and they confirmed pcos. My doctor wanted to try metformin first despite me being healthy weight. due to my age and because I had been on depo. I started on 500mg a day and the day after my first tablet I got my period (something that doesn't happen regularly) I'm now on day 16 of my cycle and I've just done an opk. Please tell me is this a positive or nearly a positive? I've had a dark line but never ever as dark as the other line like this before. Can I please have some opinions?
