Pregnant on the pill

I am having lotsss of symptoms this month... I barely bled on my period. Shit barely even had a period.. and didn’t bleed for the full 7 days like I usually do either. I started taking the pill in feb. now I know over time, your periods get lighter and the pill also mimics pregnancy symptoms. But I also have been having other symptoms as well. I have been fighting with discharge for least two months now... to the point where I got tested for stds and bv but came back clean for both. Today, my stomach has not been happy. I wouldn’t say nauseous but definitely on the uncomfortable side. However hubby had the stomach bug two days ago. What were your symptoms If you got pregnant on the pill?
