nooo.. the only thing really bad is that you can't take half of the medicine that you probably use too. lol makes for a miserable sickness! I'm sick right now too, horrid sore throat and cough lol and when I went to the Dr last time I was sick they were just like that sucks stay hydrated!
No. You're more likely to catch colds and stuff during pregnancy than you are when you're not pregnant. Just look up or ask your doctor which medicines are safe to take for sore throats.
