Very nauseated

I’m roughly about 7 weeks 4 days and I’m been very nauseous. I have been feeling like this for about two weeks and only vomited once or twice but felt nauseous all day long and even night. I’ve also been struggling to eat and drink because nothing tastes the same. Has anyone felt like this and is it normal?? I’ve tried ginger biscuits and it hasn’t helped any suggestions ??
