I’m Confused 😫 Help

Sarah

So I’ve had unprotected sex a few times for the past 2 weeks (yes I’m STUPID 😒) and my period was due on Monday 14th, I had cramps days before and up until now but no bleeding 😐 I had a little blood on Monday but only when I wiped and that was once, since then I’ve seen no blood but I’m still having cramps, should I be worried ?? Should I take a test ??
