Flying should not be a problem. After years of Endo, cysts and several surgeries to correct the condition, I was able to have twins w/no problems. Hope all goes well w/you!!!

I agree with what Babypooh says. There is no increase in risk with flying. Your fertility will likely improve after your surgery and even if they have to remove one ovary (and they will try not to remove unless necessary - ensure you talk about this) the other one picks up the slack within a few months and continues to ovulate on a monthly basis. Hopefully (your cyst is on the cusp of being too large) your doctor can remove via laparscope which only requires a 2 week recovery. Do ensure you find out more about what type of cyst it is. And fibroids are a very common benign issue for many women. Good luck and keep us posted!
I know how hard it can be to deal with the news of having a big cyst, honey. Try to calm down and find comfort in knowing that most are benign. You can certainly go on to have children and will have more chances of conceiving after the fibroids are removed, as they can decrease your chances of conceiving by up to 70%. Cysts can do that too, depending on what type they are. Did they tell you if your cyst is simple or complex? Either way, dear, remember that truly, most are benign. They can just be a hassle to deal with. Perhaps the excruciating pain you felt was due to another cyst rupturing. That can certainly cause that much pain, but if that was the case, it should subside within a few days. You still need the others monitored though.
Cysts can also cause pain by twisting. Ask the doctor lots of questions so you know what's going on. Try to relax and take things one day at a time without torturing yourself with thoughts of "what if". It's hard not to, honey, but really try not to :)
As far as flying goes, I don't think that would be a problem. I have never come across any information warning against it, but you can certainly ask your doctor about it if it would make you more comfortable.
Keep us posted and good luck! Try not to worry!
