Headaches, nausea, and diarrhea

Julie
I have had a hell of a day. I have been battling terrible headaches off and on for over three weeks. Today took the cake and I thought I would have to go to urgent care. I had it all today and have two older kids to care for.
 We haven't announced we are pregnant yet so feel like I can only ask here. 
What are you all doing on days like these to survive?
