Hi mama! M2 malunggay tea is usually started around 34-36 weeks ng pregnancy, though some moms I know started earlier, kanya-kanyang preference talaga, and mas better if you check with your OB first para sure sa timing for your pregnancy. As for effectiveness, a few of us tried it and honestly, ang feedback is mixed, some swear na tumubo talaga ang supply nila, iba naman di gaano nakita ang difference, so it really varies from person to person. Para safe at sigurado na okay lang for you specifically, best to ask your doctor or midwife about it, lalo na if may medical concerns ka.
