Hi Jodi,
I'm in the same vote, terrible cold, I've been told vicks vapor drops and butter menthols are fine, but to watch how many you take they should only be taken occasionally. I was also recommended to suck on hard boiled lollies, as the main idea is to keep your mouth wet, I've been gargling 1 teaspoon of salt to 600mls of water as recommended by my midwife. You can also take cough medicine if your coughing, but check with your chemist which ones are ok while your pregnant.
Hope this helps and your better soon!!!
