Need energy

So my last pregnancy I was sleeping all day and night even when I wasn’t sleeping I was in bed and I was miserable at first I was active but then morning sickness kicked in and stayed the whole 9months and just to a store I would get black outs

This time I want it to be different I’m 15weeks and recently applied for a seasonal job god hired on the spot over a phone interview but I only wanted to do part time but they hired to for full time 40hrs I didn’t even know if I could handle part time i feel so over whelm when ever I stand for a bit and this job will be standing for a long time

I took the job cause that’s the only one that called back and I need to be active and it would be healthy for me both mentally and physically

So any advice ladies

How do you working mommas do it
