Large and tender boobs at 7+5 😫

Megan • First pregnancy-----Due in October❤️
I will be 8 weeks on Wednesday and yesterday went bra shopping because my boobs have been extremely sore. Normally my boobs are very small and I normally wear a 32 B yesterday I got measured and I'm already a 34 D ! 😵😫 is it normal for them to have gotten so big and sore at such an early stage of pregnancy?? They throb so bad.
