11dpo so for all bfn's

Abbie
Someone give me hope! I never get sore breast/tender nipples and they have been sore for 3-4 days now and I'm also exhausted. Still getting negative tests though. af is due Friday. With my first pregnancy I got a faint positive 13dpo. Feeling like I might be out but so confussed on why my breast would be hurting and the exhaustion. Encouragement please!
