I'm just confused!

So about 6 days ago I was having some random, quick stabbing/cramp like feelings in my lower right abdomen and I didn't think they were related to AF because she wasn't due for about another week. 2 days after that I took a First Response hpt and got what seemed like a vvvfl. About 2 days ago my nipples got pretty sore and have continued to get more sore, and today I started getting some mild cramping which usually means AF is right around the corner. AF is actually due today. I decided to take another hpt, but this time I used a cheaper Walmart brand because I heard some negative things about First Response giving false negatives due to a prominent indent line. And I got another vfl! Anyone else ever had something similar happen? And did you end up being pregnant or did AF come?
