Am I pregnant

I had unprotected sex on the 30th of September. He pulled out but a couple minutes later we went for a second round. I’m on birth control but I was late a couple of times tht month. But not anything pass 3 hours. My period had also just finished. Now I’m experiencing very mild cramps. Kinda like the feeling of needing to pee. Is this a sign I’m pregnant? I’ve also been working out a lil cause I’m trying to get “thick” and I thought maybe Thts y. I’ve also only been on the pill for a month
