Before I got on any BC my period were very sporadic like I could go 5 months without a period. And they were were very heavy once I finally did get it. I remember having an ultrasound when I was like 14 and them telling me I had cysts on my ovaries but they told me not to worry and they never did anything. So then I got on BC for 5 years and just got my implant out last November. I had 1 period the beginning of December then another at the end of December and haven't had one since. We are TTC and all tests are negative :(
