I’m on BC pill, am i pregnant? Help.

I feel like i could be pregnant but then again I’m on the birth Control pill. I know there is always a chance but it’s only like 0.1% right? I’ve been on the pill for 2 months, about to be 3 months. I am currently on the 3rd day of my placebo week. Last month i received my period on the 4th day of my placebo week. But now Yet still no period but i am experiencing heavy bloating and stomach cramps and tender breast. I take my pills correct every single night, never missed a pill or anything.

I am 17, i am just scared because my bf came in me like 3 times after my last period. Basically somewhere in January it happened.

Does it sound like its just my period coming ?

Like fr tho what are the chances of me being pregnant when i take my pills correctly? Rare?
