You can also take robitussin dm, and cough drops. I got sick for awhile while I was preggo, and I drank lots of hot tea with a little bit of honey in it, while taking the musinex and robitussin. Also a humidifier might help as well. If it gets worse, then call your obs office and get directed to the on call dr if their closed. They should be able to call you something in. We had a bad ice storm while I was sick, and I was able to do that and get some meds.
It dosent hurt the baby,i had a bad cold early in my second trimester and my throat was so sore,my cough was bad,i took Tylenol cold n flu which hepled the symptoms a little but what helped me was drinking warm tea in the mornings and right before bed
