Don't worry abt it! 30 wks still too early. Boobs typically leak aft 35th wk. But not all have it and tt's perfectly fine too and definitely NOT an indication if u hve enough milk or not! If u happen to hve it, u can try expressing, store in syringes and freeze. But do be careful and not to overdo it if it comes before 37th wk as it might trigger labour.
It’s normal. I too during pregnancy there’s no sign of breastmilk. But after giving birth, the lactation consultant taught me how to massage and my breastmilk kicks in. Don’t worry too much. For now, take good care of yourself and your lo inside you first.
