i have been fighting the same thing. i use a saline rinse and Clairton. hot tea/lemonaid with honey in it does wonders for a sore throat. just make sure the lemonaid is actuel lemonaid (countrytime doesnt count)
that's pretty much if not exactly the list my high risk and regular ob gave me and I was 11-12 weeks with twins. so you will be fine. you can try some more natural remedies to if it would make you feel better. try standing in a bathroom and have the shower really hot the steam helps. sore throat take a spoon full of hunny right before bed. an ice pack on your forehead does wonders for a headache also.
