Aw mama, hindi normal yan, a few of us had discomfort sa first weeks pero persistent migraines with dizziness sounds like something you really need to bring up sa doctor kasi it could be dehydration, hormonal, o something else na kailangan ma-check talaga. In the meantime, make sure you're drinking tons of water before and after pumping, eating properly, at resting when you can, pero please don't push through the severe headaches, your health matters din para sa baby mo!
