5 weeks

Britanny

Hi everyone. I'm 5 weeks, 20 years old (7/8/97) & first time pregnant. I Can't stay out the Kitchen! I'm always hungry, I work (MedTech) and usually walk/stand on my feet for 12 hours 5 days straight. I don't feel the need to exercise, and when I don't work, I'm usually mopping, vacuuming, or gardening at my house. Is this normal for 5 weeks? Also, being a Med Tech, I would like to know if pushing a 5-10 lb cart safe?
