Maybe pregnancy?!?

Okay so my bf & I had sex on the 28th of June which is the day I was supposed to start my cycle we didn’t use a condom but when he said he was gonna cum I took him out of me & sucked his dick I know I tasted his cum bc duh I’ve blown him before & I know what it tastes like but then he said lemme fuck You again so I thought nothing of it & we fucked again but we had to cut it short bc I was worn out & couldn’t take anymore lol I asked him multiple times & he said he didn’t cum in me ... so I️m 10 days late for my period & normally I️m always late like I can be weeks late at a time but this was the first time that we had sex without a condom so I️m kinda scared to be pregnant. I️m going to take a test if I️m 14 days late bc google says to wait 2 weeks um so if y’all got any advice or anything like can I possibly be pregnant?
