Pregnancy tests

I took these a week ago!! I’m still not certain if it’s water lines I’m seeing, or an actual positive result!! Cause when I take a clear blue, I don’t really get an result at all on them. But three of these test looked positive! Iv taken dollar tests and they haven’t showed any lines either. But I feel different. Like I taste metal in my mouth, have been for three weeks now, and my belly feels bloated. Iv had a couple days to where it’s felt like someone had uppercut my boobs as well!! My husband says I’m not pregnant. But I’m not sure. I wanna say I am. I’m honestly scared.
