Has anyone else had this?

So I've been sick all week. Saturday started with a sore throat. Sunday and Monday I could barely breathe because of nasal congestion. Tuesday I was throwing up all day. Wednesday I had diarrhea and Thursday I'm throwing up again.

I'm 25 weeks pregnant and my morning sickness has subsided a little. This doesn't feel like morning sickness. Also. I use to be allergic to coconut. I use to break out in hives and my throat would close us but now that doesn't happen I hate a cake that had coconut in it (I didn't know until I ate a couple bites but that was it I didn't even finish it) could that be why I got sick? Then Wednesday by the end of the day my diarrhea subsided and Thursday I woke up vomiting but I assumed it was because I over ate the night before. Is this a bug or am I just having bad luck this week? For the most part I'm keeping myself hydrated.
