Me and my boyfriend had unprotected sex, but I was currently on my period. It's been about a month and I didn't get my period. Should I take a test???😭

Now, the story behind is... I was really horny but I was on my period. So I was like hey babe lets have sex. He was like aren't you on you're period and I was. We just went on and had a really long hard bang. After I was like you were amazing, what condom brand did you use. He said none. And then we just had sex again. I just didn't care then. But now I regret it. He is a really sweet guy but what if I am pregnant. We're not married. He and I both have very time consuming jobs. WHAT THE HELL AM I GONNA DO?? Please help?? Comment please!!!
