Will it make me a bad mummy??

Sareece • My name is Sareece me and my fiancé been together 2 years now we sadly had a miscarriage last year on 22/10/14.
I've got a job as a carah with NHS I start my training on the 17th Jan. But me and my partner are trying for a baby if and when I do get pregnant will I still be able to work my partner going to be a stay at home dad as he cant work through medical I want to work till I physically can't and go back to work soon as I could buy scard it will make me a bad mum for wanting to go work soon as I can. My last boss sacks me when I got pregnant as it was bar work In a golf club. My new job is shifts be 7am till 2pm the the other one is 4pm till 10pm but you don't do both in one day. I'd want to work till about 8month incase baby comes erlie and go back when baby about 12weeks old will it make me a bad parent???
