Chemical pregnancy?

Shy
Have been having unprotected sex.
Started on bc August 1. 
Missed my period. 
I assumed I could have missed it because the pill. But being paranoid I took a pregnancy test
It was positive. 
The next day I started to bleed. It lasted a week. 
I then took another test early evening one day and it was negative. 
Took another test this morning and it was negative. 
Did I technically have a chemical pregnancy
Has anyone experienced one and is willing to message me?
