Confusion! Please help!

Brianna
Okay so I had sex about a couple weeks ago and two days ago I fell on my period. But it only lasted a couple of hours. The next morning there was no blood on my tampon. And as of rn I'm technically 3 days late. 
And this is where you might get confused: 
I had sex again with the same partner yesterday, twice. Both times we used a condom but it broke and he came in me both times. I took the plan b pill and a pregnancy text. It showed up negative.
But I still haven't officially gotten my period and I normally have a regular cycle. I'm not sure what to think. Can anyone explain this to me 😭😩😩💀😩!
