I am a little over 5 weeks out PP and breastfeeding has been going great! The night before last though, I woke up with my right breast (only) engorged. It's normal to wake up with them full but not painfully engorged like this, and like I said, it was only my right breast. Then, again last night, just my right breast got engorged again. It's also very lumpy and tender, I'm really starting to get concerned with Mastitis. DS is hitting a six week growth spurt so he is nursing more but wouldn't both my breasts be more full if it were increased milk supply due to him nursing more and they wouldn't be this engorged, would they?
