Ovarian cysts during cycle

Ha

Okay ladies, i started my period 11/23. Which they normally last anywhere from 5 days and I’m on a 30 day cycle. On the 24th while i was showing i felt like someone basically blew up both of my ovaries and squeezed them. They hurt soooooo bad. The pain was definitely not period cramps. Then a few hours later while my husband was driving i pushed my butt up and lifted it up from the seat because i felt that pain again. I had an abdominal ultrasound today, and my right side showed at 3cm cyst on my ovary. Has any of you ladies had these pains before, or had cysts on their ovaries during their cycle? I read somewhere you shouldn’t have cysts on your ovaries during your cycle and that this sounds like An egg released from my ovary like i ovulated. I know i didn’t just ovulate so that can’t be the answer because of tests. Just worried because I’m trying to get pregnant. Don’t want this to affect me.
