Need help?

So I started the pill May 6 , had my regular period May 28 to June 1. Cool right ? Then I was spotting for bout a week In june .. I haven’t been taking the pill regularly like I’m supposed to . I had unprotected sex with my bf the 15 (yes he finished in me) lol trying not to be so blunt 😭 but I went to the bathroom & seen light pink as I wiped today . Idk if it could be the pill or something else .. any options ??
