Anyone else?! Anxious first time mum

Had the worst experience this morning in work all of a sudden nausea started along with some uncomfortable cramps and full body sweats. I had to sit on the toilet floor for about 10mins praying it would pass. Has anyone else experienced this?? I managed to run my wrists under cold water and came back to my desk and had more water and some toast. I feel ok now just a little light headed. I’m 5w 2D thinking this could be the start of morning sickness but also a little worried!!
