did you have a transvaginal done to see what type of cyst it is? fluid or complex? and how long do you think its been there? hang in there...most cyst are 90% or more for being benign.
I can only tell you this, please go get some surgery ASAP!
I have 7.5CM simply cyst on my left ovary and am taking higher dosage in BirthControl pills.
Have you consulted your OBGYN yet? If not, please do ASAP.
Missing a one day of tablet isn't a big concern but you need to talk to a doctor and find your options.
you have 1 large simple large cyst? I'd get that out very soon because you could have more or even 1 that ruptured.
