Sick most of the night?

Hi ladies. I was wondering if anyone else is going through the same thing. I have been waking up at about 2:30am-3am with nausea and pressure in my lower abdomen. Makes me feel like I could vomit, but instead I have got to go number #2 and it's diarrhea like. I am also pretty queasy throughout the day. I am 4 weeks 1 day today. Is this a normal part of morning sickness? I am not getting all of water I need to get. I already know that.
