I need advice please?

So I'm 7DPO, I have tons of symptoms, and of course I'm in my TWW and I really want to test Bc I'm so tired of waiting to see if AF shows up, I wanted to go get FRER but the hubby says they are too expensive and I need to just wait it out.. But then I was thinking if just going to go get some dollar store ones for cheap but will they even show up yet?!? What should I do? I know a lot of you ladies have been where I am and felt the way I do about the wait every month.. Help?
