Super sore breast!! ?

Danyel • TTC Baby #3
For the last couple of days my breast have been extremely sore. So sore, I can't even stand my clothes rubbing against them. I've been TTC for a month now, but recently got two BFNs (earlier this week). I normally don't feel this and AF isn't due for about another week and a few days. Can I be pregnant or am I overthinking it all?
