What's going on?

Tionya

My period is late. But I took a pregnancy test and it said negative. I'm about 2 weeks late...

Anyways. This has just started 2 days ago. Anytime I pee and wipe Its a faint pink color. So I'm thinking maybe its about to start but this been going on for days. I had severe side pain yesterday I almost had to leave work.

Input anybody?

Also I made a doc appointment because my period always shows up so this is a little strange.
