What is this?!!!

Dajee • 20. Mommy. Biz major.
Can someone please tell me the difference 
I have pregnancy symptoms: cramping, white discharge, frequent urination, heighten smell, fatigue, appetite increase, varicose veins. 
My expected period was March 6, 2016. I could have gotten nutted in:February 13,14,17,26,27. For sure the last two dates. 
I missed my period yesterday. However today around 2 pm I wiped and I had blood that was pink/brown/dark red. I put a pad on, and it was like spotting I only get a decent amount of blood if I wipe.... So I had the pad on from 2:30-7pm and there was three spots dark red. I wiped and it was dark red. Usually when I start my period once the blood is out its bright red, and it's constantly coming out on the pad. Could this be implantation bleeding or is this my period? Either way I am waiting to see if it gets heavier or turns into a bright red, I want to mention it to my
Boyfriend but the first thing he's gonna think is I'm not pregnant and I don't want this to implantation bleeding and get a positive in a few days either.
