Ran completely down

Hey y’all I’m 8 weeks pregnant with my second baby. We have a two year old daughter. I had no sickness at all with her none whatsoever. This pregnancy I’ve been throwing up, super nauseous, extremely tired you name it. The last few days I haven’t really been nauseous no throwing up etc but I just don’t feel good if that makes sense. Resting as much as possible but life with a toddler lol just wondering if others just feel ran down like I do currently.
