So my husband takes me to the ER last night to get checked out because I have thrown up non stop since friday. I can't even hold down water. also I have been having bad cramps since Friday and started spotting a little yesterday. The ER checked the babies heart beat and checked my for a uti and told me I was fine to go home. Like really I came because I am pretty sure I'm dehydrated since I told you I haven't held anything down in three days I'm light headed and dizzy. But did they check to see if I was dehydrated no. did they give me something for nausea so maybe I can hold at least water down no.
