Am I pregnant?

I was supposed to start my period on the 6th of February.. I am almost a week late. (1 more day until a week). I feel bloated, my nipples look bigger/they're tingly, I pee a lot more than I used to, having a lot of different/random cravings, & I've been constipated. I want to test soon I'm just not sure what the best tests are.. I thought about first response & the cheap one from Walmart for 88 cents (first signal) or even a dollar tree one. Any advice/thoughts? Thank you.
