Literally everything you do, medically or otherwise, will have risks, and some people with ulterior motives like to use those very minor risks to frighten people out of taking control of their own reproductive systems. Don’t let the meanies scare you.
In my opinion (and in my personal practice), birth control is an amazing way to get some sugar without worrying about pregnancy until you want to get pregnant. Go to an OBGYN you trust, talk to him/her about your concerns. Discuss the enormous, lovely world of birth control options open to you, like pills and IUDs and copper things, and try one out. See how it works for you, and if it feels weird, go back to the doctor and try another kind. Trust doctors more than you trust the Internet, even me.
I am not a medical doctor and cannot explain ovulation to you in any real clinical way, but I do recommend getting an app like “Woman Calendar” to track your own cycle. It uses a combination of tracking when your period happens, what it’s like, and if you want extra credit, tracking your temperature when you first wake up in the morning. For those of us that feel like our bodies have no rhyme or reason, tracking my menstrual cycle has been really great in helping me get to know my body in a way that I thought only doctors could really “get”. It’s your body. It’s good to know when you’re ovulating, regardless of what you want to do with that egg.
So get the app and get to a doctor to find out more info. Don’t be scared of risks. The thing that fights fear is education.
