Is it wrong?

I started a job as a bartender at a restaurant 2 weeks ago.

When they interviewed me they asked how many shifts and I said since I am still at my other job really only looking to pick up 2-3 shifts ( biggest reason is the other restaurant i worked last year took advantage of me and i got burnt out really quickly) but I don’t mind picking up some if someone calls out if I am able to do.

I picked up a shift Monday since someone no showed.

On the schedule they put me on Wednesday- Saturday (yes Christmas eve) 3-close. They JUST put the schedule out for next week which happens to be CHRISTMAS DAY opening at 10:30 am til the bar dies down so who knows when.

I’m already missing Christmas eve with family now I have to miss Christmas Day?!

And having me work Thursday-Saturday this coming week 3-close.

Not to mention I’m 6 weeks pregnant and work my other job Tuesday and Wednesdays.

Is it wrong to talk to my manager tomorrow and tell her that I really can’t be working all these hours? (I also haven’t told them I’m pregnant since I found out literally the day I started) I’m exhausted to begin with but being pregnant makes it worse.
