Am I Pregnant?... What is your opinion?

Me and my boyfriend had unprotected sex two days before and the day before I ovulated and also the day of ovulation and after. We did it again four days after ovulation and one small drop got on the outside of my vagina. I ended up being 3 days late (I am never any more than 1 day late) when my period finally came it was VERY light, it started out brown but got very dak red and kind of stringy but it was only like that when I wiped. That lasted about 3 days at the most and then it turned brown again for 2 days and then it was gone. For the past week I have been waking up very sick to my stomach and it lasts all day and I have small cramps every now and then but they arent bad. My nipples were a little purple a few days ago and I have had a little bloating, my breasts were a little tender, I have been very tired, chocolate tastes ALOT different to me and I have been itching all over. We arent planning for a baby now but we wouldnt freak out if I was pregnant because we both want one.. one day. Please give me your opinion?.. If I still feel like this in a few days we will get a pregnancy test.
