Sorry but just realized an important msg that I missed!
Forever- just wanted to say, I realize that the docs know best and all that but just thought I would share my story. I was found to have a cyst on my ovary when I was 5 weeks pregnant and it measured 3cm. By my 12 week scan it measured about 10cm. My obstetrician insisted the cyst come out as it was restricting the room my baby had to grow. At 16 weeks I was rushed to hospital in agony and the cyst was removed in an emergency op. Turned out the cyst was 20cm!!! They tested it and it was cancer!!! I had chemo and was lucky to give birth to a healthy baby boy despite all the complications. I'm not trying to freak you out and it is highly unlikely that your cyst is anything like mine, but just be sure that the docs keep a very close eye on it. Even just to make sure it doest grow and cause problems for you when you DO become pregnant. Having said all this, some people have cysts for ever without any problems. Fingers crossed it will just go away on it's own.
