Legitimately terrified at this point

I’ve been having lower abdomen weird feeling is the only way i can explain, below my bellybutton. It’s not cramps, it’s a consistent heavy, full feeling with occasional twinge of pain. Every single time i try to research why i would be feeling this way it says I’m either pregnant which is highly unlikely, i have ovarian cancer or colon cancer. I can go to the bathroom and have so it’s not constipation. Does anyone have any idea or has anyone ever felt this before? It’s gotten to the point where it’s frustrating and scaring me and i don’t know if the issue is bowel/intestine related or uterus related.. someone PLEASE let me know
