Will it be too early to buy new bra at 35weeks?

Yes. I would say still too early. My breast didn't grow much during pregnancy. But during breastfeeding, it went up two sizes! So best not to get during pregnancy time. Unless its really too small. Or you can buy slightly bigger

You may want to buy it early third trimester. I got mine around the first week of the third trimester.

If your breast have grown a lot during pregnancy, you can more or less judge the size during breastfeeding.

nope, as breasts will be expanding. i bought when i was in trimester 2.

I bought it early pregnancy.
