I feeling sick dizzy tired period in two to three days am ttc could this be pregnancy symptoms im having?

Take care of yoursel. Usually pregnancy symptoms don't start until a few weeks after the missed period. But why not check a home pregnancy test or go to the clinic if you are concerned? Have you had a fever or been around someone with an illness that you might have caught? Are you getting enough sleep? Are you eating right? Drinking too much alcohol? Get a full nights sleep and if you aren't better see your MD.
