Came out pink

Okay, so here's some background info-

I'm on the pill and I had messed it up right before my period, I didn't have sex near that time though.

I am sexually active but I use condoms and as stated before, the pill.

My period was late for 6 days, and I had normal discharge and normal pre-period symptoms.

Just a few minutes ago I got cramps and I went to the bathroom and wiped, it wasn't a lot of blood, but a small amount. It was very very light.

This isn't a "am I pregnant" post, it's more of a "what do you think" kind of post. I had a few other things that could have made my period late (stress, extreme exercise) but I just would like to know if this has happened to anyone before, thank you for your time
