I also have pcos with almost no periods in a year and managed to conceive in 2013 with the help of ovarian drilling operation done by gynaecologist in Uk.
I tried to conceive again with clomid and 2016 november and fall pregnant but had miscarriage and again fall pregnant natirally in January 2017.
I was eating low sugar and low fat diet which helps in Pcos and also was taking Moringa tablet (herbal tablet) which helps with pcos and conceiving.
