someone please help me 😭😭😭

I was suppose to get my period on Sunday and it didn't come. It's not always on time and I had sex that day. We used protection but he wanted to do 69 and I'm scared that I'll get pregnant because after we had sex I gave him a bj and then we kissed and we did 69 and I'm scared that maybe the sperm will go in me and I'm just really scared right now 😭 someone please help me 😭😭
