About this symptom


With the many early pregnancy discomforts like nausea, fatigue, bloating, gas and tender breasts it is no surprise you may be feeling irritable! This coupled with the surge of hormones and inevitable excitement and stress that accompanies early pregnancy you'll be lucky to escape this symptom all together. Like many pregnancy symptoms, this one too should subside considerably once your hormone levels stabilize and some of the other unpleasant symptoms diminish, around the second trimester.
