Too excited too fast

I'm like 95% sure my period is two days late because I've been SUPER stressed lately, but that 5% chance of pregnancy is making me stupidly happy (I have secondary infertility due to unknown reasons so I don't bother with birth control)
I haven't told my hubby that I'm late, not after two years of unsuccessful trying. It'd break his heart if it's a false alarm.  It's most likely my stress levels....
But what if it's not?!? I want to test so bad but it's too early 😰
