Stomach bug or pregnancy ?

Wasn’t sure if I should be concerned or take any extra measures, but I am currently 13+5 and having a god awful day. My morning sickness had been horrendous (I am pregnant with twins) to the point were I lost 26.6 pounds since the start of the pregnancy. I was put on a strict diet and am working with a nutritionist to stay healthy. At 12 weeks, my nausea stopped, and for the past few days I’ve felt like a normal person again. I’m still on a strict diet so no crazy unhealthy food or risky undercooked meals for me. Today I woke up head to toe sore and lethargic. I even compared it to the flu when talking to my husband, but no other symptoms. Now, it’s been over 4 hours that I cannot be further than 10 feet from the bathroom. I’ve even run out of bile and just dry heave over and over. No diarrhea or stomach pains. Is this just more pregnancy stuff or should I go to urgent care?
