Boobs 6 months pregnant

Oo, totoo yan! Six months in, ang boobs ko talaga namumukod-bukod na, parang nag-harden sila and super sensitive pa sa touch, one of my mum friends said same thing happened to her, parang nag-prepare na ang body for breastfeeding kaya ganyan. Normal lang yan, pero if sobrang sakit or may weird discharge na, better check with your OB para peace of mind lang natin, di ba?
