Having issues

So this is my second pregnancy I'm 8 weeks and 2 days and this pregnancy feels like it's taking such a toll on me already. I'm so tired and nauseous and gagging all the time where as with my first pregnancy I didnt really have symptoms. I feel like poop and have been calling off work lately because of it. Well my job makes me feel bad about being pregnant again with my manager saying I need to keep my legs closed( she has 4 kids of her own). This all just makes me less motivated to go into work. Am i just being lazy?? My son is 15 months old and I do the majority of the cleaning and cooking at home although hubby has been making dinner bc I'm too tired to after I get off work. I feel bad for missing work but I also know it's not a crime to take care of my self and new baby growing.
