Insomnia and fmu

Ange
Af was due today she didn't come I want to test in the morning but my anxiety is high and I think I will be up all night. What would you consider a good fmu time if that's the case. It's my husbands birthday tomorrow 2-12 and v-day comming I'd love to finally get my BFP after q.6 years and 3 Mc ♡ thanks good luck
