Stomach bug, food poisoning or just morning sickness?

I'm 15+2 weeks and since week 13 I've been feeling ok. Some nausea here and there, maybe a little vomiting in the morning and then I'm fine. This week I've been doing ok able to eat and get out of the house, do some chores around the house. BUT TODAY, I have been in bed all day. It's 1pm. And I can't see myself getting out of bed at all. I can't go a half hour with having diarrhea and feeling majorly like I'm going to vomit. Well about a half hour ago I did vomit and I thought, maybe I just needed to get that out and I'll be ok now. NOPE. I feel like I'm going to be sick again and I have to get up and use the bathroom AGAIN for the 5th time today. Last time I was this sick I had to go to the hospital and they told me my wbc count was high, meaning infection. S9 I thought ok I either got food poisoning or had the stomach flu like alot of ppl around me were getting. Idk whether I'm getting it again or if this is just normal. Have any other ladies felt like this and it was just a bad case of morning sickness? Or should I say all day sickness. I can't eat, I can't drink much. And right now I can't go to the dr bc I can't drive myself and I have my 5 year old daughter. I'm miserable to say the least and I'm not sure what to do. Any advice or experience with this?
