AF was due on Sunday 7/9?

Good morning Glow community!

I appreciate you taking the time to read my post and any feedback you may have for me.

We're currently TTC our first, and it's been roughly 4-5 months with no luck. This month, AF was due on Sunday (I think 3 days is an ok time frame to wait, though, right?) and has yet to show. Today is cycle day 34 for me, and I've got no symptoms other than the usual mild cramps. I took a test on Saturday morning and got a BFN, so I'm not sure if that's the verdict or if I should retest soon or wait the week out?

Kind of hoping I'm pregnant, but also know it's highly unlikely and I'm just late for other factors (stress or stuff like that). Any thoughts?
