sick!! sick!! sick!!

hey guys, I was wondering if anyone has been as sick as me since there third trimester started...
I have been coughing, had a sore throat, blocked/stuffy nose and when I cough at night it has been so bad that I have been vomiting and sometimes the coughing gives me heartburn as well... also today I got an irritated eye that sometimes leaks water.
if you know what it could be let me know and what I could do about it, please tell me. I want it to stop as I can't sleep at night.
I went to the doctors today and she gave me stuff for the eyes and the throat and the nose, but she never really told me what it could be and/or what the cause could be.. I just want to sleep
