I just spent $80 on four nursing bras. I have gone from a 30-B to a 30-DD. My breast are so heavy! I just started getting little pink stretch mark looking sorts around my nipples. I'm kind of freaking out because I have a three year old son and not one stretch mark but this time my breast are just so engorged. Do you think these might lighten up and go away? I'm only 22 weeks..I feel like this can only get worse :(
