Sudden morning sickness?

Emily

I am 16+1 weeks and haven’t puked up to this point. I got this annoying cough yesterday and this morning my boyfriend made me some tea, and about 45 minutes or so after drinking it I suddenly threw up. Not sure if that’s normal or if it’s just from me coughing quite a bit. I have a doctors appointment today so I plan on asking about it but I was just wondering if anybody else had experienced this.
