Had enough

Kelly
I'm currently 11 weeks today with my 3rd child. I wake up exhausted I'm sick all day and when I'm not being sick I feel sick, I have cramping pains throughout the whole day probably from being sick, I've weighted myself and am currently 3lbs lighter 😁, and to top it off I have to have a injection put in my belly everyday through the whole of my pregnancy and after baby born so I can carry baby and so I don't end up with a dvt.... I feel like I've been run over by a bus all the time. 
Does anyone else feel this way or did feel this way... When will it stop please help! 
Any advise is so welcome please 😘
