Pregnant and ALWAYS sick

I am 6+1 weeks pregnant and since 5 weeks I have literally felt like I have a terrible flu 24/7, there isn't a second I don't feel nauseas, exhausted and just awful! I have two children, 5 and 3 and I feel so horrible, I usually play with them all day every single day, whether it be park, hide & seek or activities, since I started feeling this way I haven't been able to give them nearly as much attention and it's killing me inside 😢😢😢
