Surgery Again - Hemorrhagic Cysts

So, next week I am going in for my third laproscopic surgery. This will be the second one inside of 5 months. Apparently, my body is continuing to develop what my doctor refers to as hemorrhagic cysts. I had surgery back in January to remove a hemorrhagic cyst and when I woke up, I came to find out that my fallopian tube was also removed. The cyst was growing from inside the tube. Six weeks after that surgery I went back for my follow up only to find that yet another cyst had developed. I was put on the pill ( at the time we didn't know it was hemorrhagic ). Now here I am 5 months later and ready to have surgery again in a week, only this time, my ovary is being removed as well.
I'm told that once the ovary is removed, that will prevent any further cysts from developing on my right side. My right side seems to be my problemed side. My question is will the cysts now start forming on my left ? And does anyone have any idea how or why these things form in the first place ? Thanks in advance for all of your help.

I did the birth control thing for 3 months and nothing.  The cyst is rather large and I'm sure that's the reason why it needs to be removed.  I'm just growing tired of having surgery for this only to find months later that the surgery hasn't resolved a thing !  Thanks for your comments.  I appreciate them :)
