7weeks and working

So I just had a miscarriage in nov... and now pregnant again ....Okay so I been working at a restaurant as a cashier dishwasher cleaner and all u can think of n I been cramping a lot lately... I feel like taking off time till my 1st trimester is over cause I’m scared since I was working during my last miscarriage..... should I just stuck thru work ...my boss is kinda isn’t happy that I asked for a few days off ... I’ve never worked during any of my pregnancies before until my recent one

what would u ladies do in my position
