Aw mama, yes normal yan sa pregnancy lalo na as baby grows, ang uterus mo lumalaki at nagsisikip sa lungs mo kaya parang nag-short ng breath ka lagi, maraming sa amin na preggy dito nag-complain ng same thing! But kung sobrang hirap na talaga or may chest pain, palpitations, or dizziness, please check with your OB na lang para peace of mind mo, 2 months palang kaya important na sure kami na okay ka, preg brain is real but so is taking care of yourself! Normalization lang ng darating pa, but your doc should know, okay?
