Advice ladies.....

I work in childcare normally 5 days, I’m early on in my pregnancy no one at work knows yet, but I feel like I can’t keep up with 5 days I’m already tired, having nausea & vomiting off & on all day. I’m thinking of going down to 3 days, I need to think about myself & I feel like 5 is just too much. My partner would like me to keep going as long as I can I know the money will help he also doesn’t understand why so early, but I keep feeling like I need to do this for me & the baby. I don’t want to over do it at work & it’s very easy to do so in my job. I had a miscarriage in dec so my doc has also recommended I drop days.
