Hay nako, anak, that's not normal at all, please go to the hospital or call your doctor right away, okay? Nawalan ng malay kahit ilang minutes lang is serious, lalo na habang buntis ka pa. A few of us mums have experienced shortness of breath during pregnancy (it happens!), but losing consciousness is different and needs checking immediately, could be maraming reasons, pero kailangan ng doctor to figure it out. Don't wait on this one, ha? Go na ngayon para sa peace of mind mo at ng baby mo.
