Second job while pregnant?

Hi ladies, just wanted to hear some opinions and experiences!

I work full time in an office, not too stressful or demanding, regular business hours.

This pregnancy (currently about 7weeks along) was a surprise and unfortunately I haven’t been at this job long enough that I will qualify for FMLA come my due date.

I’m thinking about taking a second part time job to help build our savings but I don’t know if it’s a good idea to take on a while I’m dealing with first trimester exhaustion and sickness.

My husband makes decent money too but can’t take a second job because he travels intermittently for work.

It would just be Target, probably, working as a cashier on evenings and Saturdays.

Anyone have any experience working two jobs while pregnant? Is it a bad idea, or worth it?
