BED REST/ HOME REST??!?

Kaylene
Wondering if anyone has been placed on bed rest- or like house rest at the beginning of there pregnancy? 
I am currently 7 weeks and been having cramps and spotting as well as bleeding , and dr said I may have to go on something like bed rest... which means quitting work as I lift, change, bathe, and look after seniors at a seniors home. I am just wondering if anyone has had any experience with this at all and was everything okay?
