Sore Boobs

Brittany • TTC since November 2014. Diagnosed with PCOS in July 2015. 5 rounds of clomid and now trying Letrezole with no luck.
I'm 5 weeks today and my boobs are unbelievably sore. I wear a sports bra at home, but can't wear one with my dresses/suits to work. They hurt so bad even the seatbelt in the car hurts. Anyone have any suggestions for relief? Will this go away?
