Hello, I'm 23 weeks pregnant and haven't been able to sleep well all night because my throat started hurting. It got worse in the morning, swallowing is painful, and talking hurts. Now there's congestion in my nose and my head is starting to hurt, but there's no fever. What do you suggest I do or take? And what shouldn't I do?
