I feel like a crazy person....obsessed with the test!

I had a miscarriage New Years Eve and had a chemical my last cycle (Feb). Just found out Tuesday we're expecting again and I'm not having the cramping but I'm obsessed with testing still. I'm taking test after test and I feel like they're not getting darker. Also just at the -1-2 weeks digital and waiting until next Tuesday to take another digital for a hopeful 2-3 weeks or even 3+ I know i sound crazy and I feel crazy but I'm just so nervous. Anyone have any advice?
