Girls, hello everyone. I have a stuffy nose and it's hard to breathe, my head hurts. The due date is 14 weeks. Can you tell me who has been sick and how they were treated? Doctors say I can't drink anything but tea, honey, raspberry, lemon, chamomile. I understand, I don't argue, but I'm afraid that complications might occur because I feel worse now. For half an hour, the nose opens up, then I breathe through my mouth again.
