Holy tits!

I feel like it's way too soon for my boobs to be getting big (6w 6d) but a couple weeks ago my boobs grew. My last pregnancy my boobs went up to almost a C near the end of the pregnancy and breastfeeding. This time I'm 6w and I've gone from 34a to almost a 32b. I told my boyfriend the other day when I take my bra off it feels like boulders falling off a cliff (because I'm not use to having anything there) but Jesus... I didn't think it would be this crazy this early.
