When to test again?!?

I’m getting so anxious and impatient and I know that doesn’t help but :/

Took a test yesterday and it was negative, completely white!

I’m now 4 days late and on CD 34!

I normally have pretty regular cycles. About 28-32 days 🤦🏻‍♀️

The only time I went past 35 days is when I got my BFP which unfortunately ended in a mmc in January!

Now Praying for our rainbow baby!🤞🏼✨🌈

And getting impatient that AF either needs to show or a bfp would be nice!
