Oo, normal lang yan, mami! A few of us first-time moms din experienced na parang walang morning sickness pero ang sakit ng boobs ay sobrang intense, it's one of the earliest signs talaga ng pregnancy, kaya hindi mo kailangan mag-worry na something's wrong just because you're not nauseous. Pero since iba-iba talaga ang pregnancy symptoms sa bawat tao, best to confirm with your OB just to be sure, lalo na if it's your first time and gusto mo lang ma-rule out other stuff. Good luck, mama!
