Don’t know what to think, HELP!

So I went home a week ago to go see my boyfriend and we had sex but we dont use condoms majority of the time.. but he did came out of me at the very last minute but he doesn’t know if there was a lot or very little.

Anyways I was supposed to get my period around Jan27/28, and I have not gotten it yet! (My period does run into the next month, for example, my December period ended around Jan4th) so I’m not sure if my body is like naw girl you already had your period for the month or idk! Should I take a test when my boyfriend comes to visit me on Wednesday?

I haven’t gotten any symptoms of my period except that my period are heavy asf, as well as my nipples are sore and constantly hard ..

Help a girl out!?
