Maternity Bras!

I am only 6 weeks and my boobs are just way too big for any of my bras! I've been wearing sports bras which is painful because my boobs are so heavy, sports bras don't provide much support. I tried buying a bigger bra but it was uncomfortable and didn't fit right. I've gone up almost 2 cup sizes!! It's so crazy!

Is this normal?? And is buying maternity Bras different from buying regular ones?
