Pregnant?

I had unprotected sex on February 9th and my boyfriend did cum in me but I took a morning after pill the morning after😂 so after that I had brown spotting every time I wiped myself. So yesterday I started bleeding but it is the right time of my period so I thought it was that but it’s very very light. I read that it could be implantation and according to the photos and stuff I looked up it looks like implantation to me. Do you think it’s my period just lighter than usual because I took the pill or I’m pregnant?
