Lol no they arent supposed to grow. Some boobs do some dont. Just depends on the hormones in your body.
Exactly , i feel like my boobs didn't grow at all. I'll be 25 weeks tomorrow .
Did you stop taking hormonal birth control? My boobs grew, but I was small to begin with. My mom's boobs didn't grow when she was pregnant with me, but she had like 4D or something...
