Vomiting should I be alarmed ?

T
So this morning I ate a big breakfast I was so hungry but a little while later I had extreme diaherra then a few moments later I started feeling a lot more sick with extreme stomach pain i threw up so much ....like everything I ate came up.☹️☹️☹️ I've never had this happen before except in my first trimester which was normal but I'm 34 weeks and 4 days. I've been trying to drink water as much as I can but I feel so nauseous... I ate a little tiny bit of food but I'm hoping it I'll stay down. :( I just hope it's not anything bad. Baby's still moving a lot which is good but me on the other hand I feel so sick and sluggish I also feel like I'm developing a fever but I hope and pray this will fade away because I feel miserable ☹️ Not sure if I should call my doctor and see because she honestly sucks or if I should just wait it out and see how I feel in the next couple of days?.
