I need help/advice, ladies.

So, this is going to be long..
Let me tell you the story before I get into it.
🔺(at this time I still lived with my parents) About 2 years ago, it was a normal day, i woke up to get my little brothers from the bus stop but I decided to go get a shower first... while in the shower, I get this INTENSE pain that I drop to the floor. I drink some Ibuprophen and lay on the bed thinking it'll go by. It doesn't, it gets WORSE. My parents decided to take me to the hospital but I couldn't walk at ALL, I had to be carried to the car. Anyways, at the hospital they thought it was Appendicitis but even when they thought it was that they couldn't come to me because they emergency room was FULL. So, I stayed in the emergency room for HOURS with this pain, throwing up nothing (because I didn't eat anything), it took SO much energy from me that I couldn't even hold my own head, it kept falling on my shoulder...
As they bring me into the room, they give me morphine to bring down the pain and take me in for a scan. While I'm waiting to get the results, they've given me morphine about 3 times and the pain hasn't gone down AT ALL. They come back with the results and nothing appears there, so the next thing is an ultrasound... 
I get my results back, and I had a cyst in my right ovary. BUT, here's where it gets worse. The cyst was SO big that my ovary was the size of a softball, AND not only that, it got tangled with my tubes and there was no circulation. Therefore, my ovary was black. There was NO way it could be saved so I got my ovary removed.
Coming back to the present, right now, on Sunday, I went to the hospital for a cyst in my only ovary left. I'm in pain right now, not as much as last time, but still in pain. Waiting until the cyst breaks with the pills they gave me. 
What I need advice on is,
I want a child. My boyfriend says he would want it when he's older but I can't wait longer. Not only because I want a child but I'm scared of losing my only ovary. This isn't the first time since the surgery that I've had another cyst. I live everyday scared of losing it and not having a child of my own. Every time I get some type of pain in my lower abdomen I get scared. What advice would you girls give me? 
EDIT: I'm 21 almost 22. 
I do want to have a talk with my boyfriend about it, i mean he knows about it and the bad side of it but I haven't had a serious talk with him about it.
