Morning sickness???

Not feeling good. It comes in waves, but when it’s here it’s not nice. I’m 4W4D and since I found out last week it’s been like this. At first I thought it was cramping, then maybe a bad case of nausea, but it comes with a feeling of having to go to the bathroom and sometimes... TMI diarrhoea . I’m wondering if this is normal. First time being pregnant and my anxiety is through the roof. Really feels awful in the moment. Usually lasts 20-40 minutes then gone again for a little while. Everything I have read so far says constapation is more common.
