Please answer!!!

This morning I shot straight out of bed because my husband was hogging the whole bed and I was going to go to the couch but then I felt nauseous so I went and sat in the bathroom. I felt as if I was going to puke but then the diarrhea came and once that was over I threw up twice and now I feel fine. The whole ordeal lasted about 20 mins and this isn't normal for me. Could it be morning sickness? My period is about a week late but I haven't had a positive test yet going to try later!!!
