One confusing body 🙃

Summer

So, my period was due 4 days ago and it has yet to show. But yet, I’m getting the cramps, and the pressure of a period but... no period. I’ve taken a test yesterday and it came out negative. It’s been a while since I’ve been this late on a period but it’s never really been like this. Is this normal? I honestly have not been TTC so, this is coming as a bit of a shock. I’m not sure if I should wait around for a positive test or for my period to start but I wish one of them would happen so I could know what’s going on with my body 😭😭
