It's probably heartburn. I have been having heartburn since the beginning of my second trimester and a sexy wheezy cough at times to go with it. Try drinking milk to lessen the burn, I find that helps :)
It's possibly heartburn...third trimester with my second and third I had the same problem, my suggestion is take zantac, especially take one right before bed. Only thing that helped me...i hope this helps,good luck!
Still have the cough a bit and the burning feeling in my throat.
Any suggestions on how to get rid of or at least lessen this?
