Going crazy!

I've been ttc for 2 months now and I'm currently 4 days into my next fertile week. I feel like all I'm thinking about is when I can test, even though I know I've still got a 2 week wait!! I keep looking at my app and over analysing things I've done/doing. I don't know what to do because I feel I could be stopping myself getting pregnant 😔😔 I don't feel stressed to be honest, but I feel totally obsessed and over took by it!
I had a miscarriage last year (not planned, but devastated to lose the baby) at 6 weeks. I'm so worried I'm not going to conceive, or when I do conceive I'm gonna obsess over losing another baby!
