Period 10 days late, want some advice


So my period is 10 days late. I’m 18 & I’ve never had sex with my bf but have done other stuff recently. Know I can’t be pregnant but I’ve been super anxious anyway. Just before I was due I had like all of the symptoms (sore breasts, bloating, even some mild cramps etc) but then nothing and they’ve all kind of gone away mostly. I’ve been pretty anxious recently just because I’m in lockdown and can’t see my family etc but I didn’t think it was anything too bad anxious/ stress wise but maybe I’m wrong. Is it possible for my period to still come this late or would I have missed it completely for some reason? I’m a huge overthinker so all of this is really getting to me & would love some advice
