Ovarian Cyst

Hello, So My gyno put me on Bc for a month because i have cyst in my ovary She said she want the cyst to go away before i can start medication to help ovulate, I know the only way to see if my cyst go away is Ultrasound, but my gyno said that if didn’t go away it she will have to drain it. i don’t know what she mean by that? It’s my first time! I also read that when cyst dissolve? Or rupture might have symptoms, I was spotting 3 days and i get the feeling of pinch or stabbing in my abdominal pain. Is that could be symptoms? Anyone have to experience this? Please share your story. Thank you.
