Aw mama, that's tough! Pero honestly week 11 onwards ay common talaga mag-start or intensify ang morning sickness, kaya iyong cough at runny nose might be triggering it pa more or making it feel worse, ang combination talaga ng pregnancy hormones plus the cough reflex can be a lot. Have you tried eating smaller, more frequent meals kasi feeling mo puno agad ang tiyan? Sometimes that helps prevent the nausea from piling up, tapos try staying hydrated in sips lang so hindi overloaded ang stomach. But if it's getting worse or you're not keeping anything down, better check with your OB just to make sure everything's okay and maybe they can suggest something safe para sa cough din. Kaya mo yan, mama!
