Can somebody please help

Samantha
so I started my period march 2nd and it ended the 6 th ! I had unprotected sex with my boyfriend days before. And after my period I discharged with of course the usual stretchy with old blood ! But these last couple of days it has been sticky like tac or sticky like a glob of dried glue with brown blood and a mixture of what looked to be egg whites . And now I'm spotting on and off with a light pink like I'm about too start my period ! I'm confused . A friend told me it might be implantation bleeding and my mom told me it's just cleaning itself ! Oh and I've had sex like crazy this past week too
