Pregnancy test anxiety.

I'm about to go but some pregnancy tests and take them tomorrow morning. I'm tight on money right now and was wanting to buy ones from 6-10 dollars. And the only ones that range from that price are the equate early pregnancy test, and the regular equate tests. I'm nervous to buy them cause I don't wanna waste money for nothing. I've read some reviews and mostly all of them were negative comments. What do you ladies think of this brand of pregnancy test? Oh and I'm 12 DPO today, gonna be 13 tomorrow of course.
