Cyst on right ovary

So, I was diagnosed with a cyst in my right ovary the 17th of August, so it has been only a few days since. It is on my right ovary and when I was at the hospital they said it was threatening my appendix as well (they didn’t tell me the size in cm, all they said was it is a significantly sized cyst). I have been taking it slow, taking the antibiotics they diagnosed, and thankfully have an appointment with a gynecologist today. Also, I should note, I have very irregular periods with my last one being May 1st-13th. Does anyone else have a similar experience and if so, how did it go/ how is it going for you?
