Putting on weight after coming off pill

[Beaverfeaver2]

I came off the pill last June ans since then have had no period and more recently a diagnosis of PCOS.

My weight since coming off pill is just increasing and more so very recently.
I am on low carb/low gi and exercising more than usual.

It's really getting me down as I can't fit onto any of my clothes any more and clothes I bought a few months ago are already getting tight and uncomfortable

What can I do???

I stopped taking Yasmin last July and put on a couple of pounds, despite sticking to same exercise regime and cutting back my calories (I record everything I eat in Myfitnesspal and have had to reduce my average daily intake to below 1,500 to maintain my BMI of 19). From what I've read I think the wait gain is due to water retention - this make sense as my appetite hasn't increased. My gynaecologist has banned me from exercising, so not going anywhere near the scales now! Saying that, if it means I start ovulating again then it's worth it

I came off my pill last March and since then I have lost 2 1/2 stone. I can't get weight on at the minute and have a bmi of 16 which is no doubt affecting my fertility.
