Hi, I had the same issue as well but have since given birth. I tried taking medication for cough and tried various remedies then but they did not work. The cough stopped immediately after I gave birth and when I was chatting with the nurses in the hospital, I learnt that it could have been gastric reflux. It might have caused irritation to the throat, leading to cough. You might want to try taking medication for gastric reflux and monitor to see whether it works. Take care!
