Working while pregnant

Working is always tiring but lately it feels like it takes more effort than before! The nausea while at work isn't fun but drinking plenty of water and sitting down when I can is very helpful. At work everyone has been very supportive and friendly so there isn't any faces or huffs when I need to be moved to a different till because the bag lifting is making the nausea worse. Or when i need to leave every 30 minutes because the baby decided to push on my bladder. So far at 9 weeks working while pregnant it no issue as a cashier at a grocery store. Except when the smells get overwhelming and make me sick lol
