complications

hello ladies...i have be TTC for more than 10 years and i found out when a few years ago that i hav a retroverd uterus and PCOS. I came off of birth controll pills over a year ago and i can't seem to have a period without them😔...my obgyn put me on two courses of clomid and that never worked, then i was put on another course of metphormin and that never worked either😧. apparently they were to help my pcos and to help me get pregnant but i have been trying to no avail. I got so fed up of taking so many pills that i decided to stop everything and just pump my body with vitamins and try to eat healthy when i can with hopes that something will work im my favor. If anyone has any suggestions please do share.
