Could I be pregnant? Please help

So I had sex the week before my period (I'm on the pill and he wore a condom) then I got my period for 5 days and on the Saturday night my period finished so I had sex with my bf like 4 times. We used a Condom each time and I took my first pill of the packed that night. Two days later I started having low abdominal pain and pressure and was going to the toilet like ever 10 minutes to do a wee. I also had heavy discharge.

The next month I got my period again. I took a test because I got my period like a day earlier and my boobs were sore as well as the other symptoms still continuing.

Could I be pregnant? Like what are the chances since I'm on the pill and he wore a condom (pretty sure it didn't break, we couldn't see any breaks) and I got my period and negative tests.

No mean comments please I'm being serious and need some support.
