Can't sleep because of nausea, is this a sign?

Bl
I'm 10dpo. I went to sleep after midnight and it's now 3am. It took me 2hrs to get to sleep because I was soooo nauseated and cramping slightly the feeling of vomitting felt like it was going to be reality. Now at 3am literally after 2min of waking up in still nauseated. The feeling won't go away!! I don't think I'll get back to sleep. It's unreal. Could this be a sign I'm preggers? 😊🤔😳😊
