feeling fed up and teary

Tricia
Been experiencing cramping pains and a lot of sickness. 
Just feel like I can't do anything at the moment without feeling sick and unwell. I'm 6weeks tomorrow 
Early scan at 5+2weeks showed x2 sacs (Twins) 
I go for another scan on Monday to hear heartbeats. Hubby has been so good but I just feel useless at the moment. 
Anyone els feel like this? Xx
