Hi. I am 21 weeks pregnant and this is my third baby. My problem is that I have a lump of mucus,i would say, in my throat and it is quite problematic. It is worse than vomiting. This happens when i wake up in the morning or whenever i lie down.I have to throw it out forcefully. Sometimes a water like liquid or yellow fluid is also coming out. This is happening since my early months whereas i used to have this problem in my 9th month in earlier pregnancies. Please help. Thanks in advance.
