Ay, congratulations sa pregnancy, mama! Pero since naka-reseta sya sa'yo at may headache ka, better check with your OB agad, important na malaman nya kung normal lang ito or need ng adjustment, especially sa first trimester. Some mums sa group ko nag-experience din ng side effects from medications, pero talaga, better safe na mag-confirm sa doctor mo mismo. Sana okay lang, pero don't wait if it gets worse, ha!
