Pregnancy

So me and my boyfriend had sex the night and day of Thanksgiving. The night, we used a condom and it popped, but my boyfriend still pulled out but I don't think in enough time because I could feel the cum on my vagina. The next morning we had sex again and we didn't use a condom but he didn't cum. My period is late, but sometimes it does that, it comes on different days of the month instead of the same day every month, should I wait another month, get a pregnancy test just in case or???? Idk someone give advice
