possibly morning sickness?!

So my period is one day late but I have no pregnancy symptoms so I have not thought anything of it. Well last night I went to bed fine and woke up about 3 hours later terribly nauseous. I went to the bathroom and threw up a lot. I was able to go back to sleep and this morning I’m still nauseous but better. I don’t think it was anything I ate because I had no stomach pain, no diarrhea, etc, but I feel like it would be too early and too random for morning sickness. Thoughts ladies?
