Oo, sterilized milk is fine during pregnancy and super helpful para sa calcium, lalo na kung nursing ka na rin, pero ang low blood pressure mo at dizziness ay concerning at kailangan talaga ninyong i-check with your OB, kahit kailan, dahil yan ay red flags during pregnancy na dapat not ignored talaga. One of my mum friends had similar symptoms during her second trimester at ang doctor niya nag-adjust ng vitamins at nag-recommend ng increased water intake plus mas frequent meals, kaya don't delay checking in ha.
