pregnant or. no? please help :(

So I've noticed that I've gained 7 pounds in a month, I have not changed my diet in any way. I might eat a little more, but healthy things. I only had a 2 day "period" and now I'm having weird cramps and I feel sick to my stomach often. Espically last night when I ate the fat off of some chicken( the only time I got sick from that was when I was pregnant with my son). I took a few pregnancy tests and I'm confused, it showed up on 2 different tests same brand same box. I know it's hard to see, I can barely see it myself. Please help :(
