Can anyone help me please, I had one ovary removed 4 years ago due to cyst, I was told to go on the contraceptive pil since then as this would prevent any follicles from developing and therefore minimise the risk of any further cysts. I have always taken my pil correctly and have been for two scans in the last year and each time been told there's lots of follicles and at the most recent scan there was a 2cm follicle. I don't understand why there's follicles when the whole reason I'm on the pil is to prevent them totally, and also if I have 2cm follicles does that also mean that my pil isn't even protecting me from pregnancy let alone from developing further cysts. How have none of my doctors picked up on this when they see the scan results? I feel i always get contradicting advice off them that's why I'm asking here. Does anyone have any information that can help me please :-(
