as early as 16-22 weeks mommy may colostrum na napproduce. though, maraming mommy ang hindi aware since hindi naman sya umaagos or nakikita agad agad unlike after giving birth tsaka sya nagleleak .
Too early po para magkaron ng milk. Normal po sa buntis sumakit ang breast especially sa first tri. But if it’s too much and making you uncomfortable, check with your OB
