Aiyoo sabar sabar dear, pregnancy cough is really the worst especially when you can't lie down comfortably! Since you're only 7 weeks and already struggling, definitely go back to your clinic or see your gynae to make sure the cough medicine they gave is pregnancy-safe, sometimes need a bit of adjustment. Try propping yourself up with extra pillows at night (helps with reflux too yang biasa jadi pregnant), drinking warm honey lemon water, and steaming your nose before bed, a few of us mums swear by this combo when we're sick during pregnancy. And ahhh I totally feel you on the older kids being extra demanding when you're not well, that emotional toll is real, so do lean on your partner or call a trusted family member for backup so you can rest properly. Hang in there, this phase akan pass!
