Tingling Breasts

I am 29 weeks 4 days and my breast have been tingling as if they are full and need to feed my baby! ( which is still growing inside me)

When I nursed my daughter before, I would get this same feeling when she was ready to nurse.

I've never experienced this in pregnancy and I almost feel like I should try pumping to relieve my boobs of this feeling... but I am scared because wouldnt it be colostrum for my new baby and doesn't she need that as soon as shes born???

Can anyone relate? What did you do?
