what's going on?

Tricia
My period is 3 days late today. To induce my period I ate fresh pineapple all day and had sex with my boyfriend and right after sex I started my "period". I usually wear a tampon but this flow was way too light and very soft pink in color (TMI sorry). So all I have on is a panty liner, I've also had normal period cramps all day. Can someone tell me what's going on?? Am I spotting? I've never had spotting before!!
