Do all womens breasts get engorged or hurt while not breastfeeding?

Since you never breastfed you probably never really even produced milk because there was no stimulation to tell your body to make the milk. If it has not happened yet then it is not going to happen. As far as the baby's umbilical cord, it can take some time for it to fall off. If it is still attached at 3 wks of age, I would call your pediatrician & check with them. Do not try to remove it on your own though.

hmmm I leak everyday and it's white..I forgot to mention that

If you are not BF & you are not engorged & uncomfortable just consider yourself lucky because most women would be. The fact that you are leaking is normal. Just make sure you are not stimulating the breasts at all & the leaking should stop at some point.

Thanks
