Waking up feeling hungover ?

Did anyone on here feel as if they were waking up with a hang over the very first month of pregnancy? I don't know if I'm pregnant for sure but I've woken up twice now feeling groggy, super thirsty, neausous but not vomiting, and with a slight head ache. Without drinking the night before. Has this happened to anyone else? Helpppppp. And if so, how many weeks would you have been?
