So I am 21 years old, I missed my period and it is about 8 or 9 days late, I had a thick milky discharge a few days ago, my nipple hurts sometimes its bad and other times its dull, I found a blue vein on one of my blobs buts it hard to see it, I wanted to see if I could possibly be pregnant before I buy a test, also I get sick after my first meal of the day unless I eat saltine crackers and if I don't get sick my stomach hurts kind of bad, I get crampy feelings like if you were on your period but yer not period, please, any answer would be appreciated.
