What can I do

I am 12 weeks pregnant today with my 3rd child and I have been sick for about a month now. It's been off and on but since yesterday it has gotten worse. My throat is on fire, my head is killing me, my whole body aches and I'm just exhausted all the time. And in so much pain. Idk what to do, I'm so over it and I feel nauseous but haven't puked yet. Is there anything I can do to make it better. I've been taking Tylenol every chance I can and been eating cough drops a lot.
