implantation bleeding.

I had my period about a week ago and it was heavy and longer than normal. day before yesterday when i was peeing i wiped and it was a very light blood yesterday at work i had light bleeeding again & this morning but it’s not consistent bleeding one time i’ll use the bathroom and it’ll be light blood and the other times i go it would be no blood. My boyfriend and i had sex during the last couple days of my period and after i’ll show my calendar below (hearts represents unprotected sex) could the bleeding im experiencing be implantation bleeding?
