Week 5 at 36yo. I started to cough a lot with sour taste on the back of my throat. I feel like this symptom gets worse with certain positions like lying down. I couldn't take a nap today because of this symptom. Lots of lots of lots of burping n frequent hiccups. I can't tell if this cough is related to heartburn or actual cold (my family member has a bad cold...) I've been very careful not to catch with frequent hand washing, hydration, eating balanced meals n so on. I don't have problem with appetite although I usually regret with the portion even when I had very small frequent meals... Help!
