Idk if I am or not

Okay so recently me and my boyfriend have multiple times of sex and it was mostly with condom. The first time we did it, we didn’t use condom. He didn’t cum or anything else. I freaked out and thought I was pregnant. Turns out I wasn’t. Then for the various types we did it with condom and this month, and on the last week of June on Wednesday we did a quicky, it went by fast and it was only like 4-5 minutes. We didn’t use condom, and nothing has happened. And this month we did it on july 12 and like I missed my period. He didn’t cum and he is certainly. About it. No precum or whatsoever. My mom and sister period cycle change and it’s probably because of that. I think I haven’t had my period because it change its cycle. I just want to know if I am or no. Too scared to do the test and I rather just wait and see.
