Vaginal dryness=yes.... How long have you been on the pill? If you've been on the pil for a while, and ths is a sudden side affect, it's most likely not the pill... I've never heard of dry mouth and sore throat as a side affect of the pill???

It's better to be safe than sorry and talk to a doctor.... It might be something serious, or something as simple asallergy season... See a doctor!

Im not on the pill any more it would not stop my period and I got frustrated with vaginal dryness even though my boy friend was very understanding. So I quit the pill and my period stoped by its self. Thank god hehe. And when I stopped the pills as well my dry mouth and sore throat went away. So im okay now hehe. Knock on wood hehe
