birth control
"I wish I never got this. 3 months after insertion I began to get extreme abdominal pain once a month due to new ovarian cysts. Now, 8 months after starting and 1 month after removal, I might need surgery due to an 8cm cyst on my ovaries. Doesn't mean that it'll happen to you but be aware that the risk is there! I thought it would never happen and that it was unlikely but here I am today."
