Anak, for something like this, especially kung may specific timing or dosage involved, kailangan mo talaga makonsulta ng doctor or OB, ha? They'll know kung safe for you and kung kailan exactly dapat i-take based sa situation mo.
A few of my mum friends took it during pregnancy, but palagi silang sinabi ng doctor nila kung paano, kaya better safe than sorry! Message your OB or drop by a clinic, they can guide you properly.
