Probably a stupid question

So I work at a beauty supply store. The strip mall we are in is pretty empty as we and two other stores that close before us are the only ones there. A lot of the times we close by ourselves which I never thought was safe. Well tonight I was by myself and the store got rubbed lucky not by gun point but I was alone and scared. Being six months pregnant really is making me worry more. After talking to my manger, dm and police I was able to go home. I broke down on the way home crying, thinking how it could of been worst and how I don’t feel safe. Is there anyway my doctor would be able to get me out of work earlier or would I just have to quit?
