it's possible to get one every time you are supposed to ovulate. having had one rupture a few weeks ago myself, and spending 2 days in the hospital because of it, i did lots of research and asked my doc lots of questions at my follow up. I still have 2 on my right ovary that we're keeping an eye on. I have follow up ultrasound in 5 weeks. other treatment is bc pills, but since we're ttc she's waiting until after ultrasound to see if that's necessary. good luck and keep me posted.
Honestly I'm not sure, I have never had one. Have you called your Dr's office? If not I would do that today and get these questions answered by them. Good luck.
