Can I get excited!?

Ti

My AF is expected tomorrow. I got a faint line yesterday and today. Been trying for 13 months, 10 month ago I got a faint line before my predicted AF and end up having an early miscarriage — the line never got darker. It was so heartbreaking! Do the lines look like they are getting darker? Can I tell my husband yet? I want to get excited but I’m scared it’s not real.
