I have a history of cysts on my ovaries. .some have ruptured causing horrible pain..i haven't had my period since february. .should i be concerned?

Ob/Gyn time!: Right now you only need to be concerned enough to make an appointment for a good exam. After results you may need to think about treatment choices, but it now all you ought to do is make a call. I'm guessing you are not thinking that you are pregnant but if you had unprotected sex, that may be the exam finding. Good luck. Take care.
