Pregnant maybe ?

Could I be pregnant ? A week or 2 ago I had this pinlish mucus come out of me after I went to the bathroom... But the first time it happened there was a little blood in the mucus just a little not even 1 inch .. I'm pretty sure I was ovulating.. But anyways after the pink mucus stopped there was brown blood in the mucus like dried up blood .. For the past month my vj has been hurting whenever I have sex .. And I've been dizzy, and having cramps since that day also I've been really moodly and emotional .. Today I felt my stomach and it is hard and my lower stomach .. Also sometimes my pelvic bone will hurt just for a few mins.. I'm only 17 and I do have unprotected sex sometimes... I get my period the 24th though but my last period was kinda light it started off heavy but after a day it got lighter ( sec 30th - Jan 5th )

Also I've been getting headaches and feeling really sleepy and my nipples hurt
