2nd Trim Post-flu coughing

Hi mommies, any remedies for post-flu cough that doesn't go away? I recovered from a cold weeks ago but the coughing doesn't go away. It's affecting my sleep, and I would accidentally pee sometimes when I cough. Phelgm is clear and watery and its like backdrip in my throat. Any mommies got this and recovered, can share how you recovered? Trying to avoid coughing syrup cos worried it might affect baby. #advicepls #firsttimemom #firstbaby
