D..
Do you want to get pregnant? It sure sounds like it.
I would stop having sex all together right now. If you aren't pregnant, that would be really good, because you probably need laproscopic surgery to remove that cyst.
Non-bursting cysts are a little scary because they CAN be cancerous. There are different types of cysts, and though the bursting kind hurt in a way that rivals giving birth or passing a kidney stone (I'm not kidding about this, having had it happen twice and pulled a muscle in my arm during one of them), at least it and the pain afterwards is over by the next day. With a non-bursting cyst, especially one YOUR size, it can cause fever and pain that can make you feel like you have appendicitis. I called the ER nurse on a Sunday night, I hurt so badly and asked her if I should come to rule out appendicitis. She asked me if I could jump up and down on one foot. I could, and she told me that it was most likely NOT appendicitis and that I should go to an urgent care center (they were VERY busy that night at the ER) to get checked out. I did, they gave me a shot, and told me that they THOUGHT I had an ovarian cyst. Turns out they were right. It wouldn't go away, so I ended up having to have surgery to remove it. It was 7 cms by then and my doctor told me that usually, he isn't able to save the ovary by the time they are THAT large - usually there's too much bleeding. He WAS able to save mine.
I had already had two kids by then, C., and didn't plan anymore. After this is when I started having the bursting cysts. They put me on birth control pills in order to stop getting the bursting cysts. It worked, thank goodness.
The point I want to make is that a cyst the size of the one you have really needs to come out. You have a lot of symptoms that I certainly think can be caused by the cyst. I really hope you are NOT pregnant with a cyst like this.
Good luck - I hope the timing of everything works out for you to be healthy, and if you want to have another baby, to get pregnant after you are healthy again.
