Needing some Glow help......

Danielle
Trying to figure out when to test. I've been getting bfn's for about a year now and I wanted to know when yall think I should test. Af is due tomorrow my breasts and nipples are really sore and I'll be 14 dpo! I was thinking about waiting till the last day of expected period to test so I won't get my feelings hurt. I'm feeling very hopefully about this cycle so that is what's makes me want to test. I've been dealing with a lot I've had 2 miscarriages last year and all I want is my rainbow baby!!! What yall think
