Hemorrhagic Cyst?

Hey everyone got some horrible news today. So I went in for my ultrasound to make sure everything was okay to start my 3rd round of Letrozole and was told they couldn’t start me

on it because I have a hemorrhagic cyst on my right ovary. I’ve never had this before..and it broke me down today because I have to take the Letrozole because my body doesn’t ovulate on its own. If anyone has any information or has had this type of cyst before please comment down below. She also said that the cyst could rupture this month and if it does than I would have to have surgery. Please share your wisdom thanks!
