Hey ladies, I’m 16 & it’s 6 November. I had surgery in June coz I had cysts on my ovaries (or somewhere in my reproductive organs, not really sure)

I got my period last week with little cramps & my next period is expected 22 November.

I’ve been having the worst abdominal cramps & it’s been stopping me from working & even leaving my room.

Does anyone have any idea on what might be happening ?
