Sayang, morning sickness biasanya muntah je without the diarrhea, tapi ada jugak some mums yang experience both sebab hormones berubah sangat during pregnancy. A few of my mum friends mentioned cirit birit + nausea together especially first trimester. Tapi kalau diarrhea tu yang sangat teruk or dengan demam, better check with your gynae just to be safe because could be something else juga like gastro or food issue. Jaga intake air tau, jangan sampai dehidrat!
