worried about pcos

So I had my monthly period last Sep 8-14, then I had unprotected intercourse (Sep 17), after 2 hours, I took Trust Pills. I js did what my classmates told me. 4 pills at 1 am and another 4 pills at 1 pm. After 6 days, I had 4 days period again. I took Diane pills after to regulate my menstruation since it’s my medicine for my PCOS. I’ve been diagnosed for 4 years now.

Still now, I’m worried if I am pregnant or not. I’ve been unwell eversince but when i took the pills, it gotten worse. I keep telling myself that it’s because of hormonal imbalance, but I feel nauseous every damn time. Aside from being worried about being pregnant, I am afraid to go to a Doctor since i noticed that even before I inter-coursed with someone, my lower abdomen is hard and I am always having cramps. Year 2022, my ob-gyn told me i have multiple cysts, and now, idk what’s happening inside me.
