Help :/ I'm getting sick

I'm almost 17 weeks now and of course I'm getting sick!! Sneezing all the time and my throat is KILLING me. No fever though yay :)
I gargled my mouth with hot water & salt to try to ease the pain and just took a Tylenol PM to try to help but I was wondering what other medicines I can take to help me without having to go to the doctor. And is it okay to get sick while pregnant? Someone at work told me it could hurt the baby.
