Need advice thinking about quitting work

[bubblychick]

Basically I'm expecting child number2 and really considering quitting work the hours are terrible and my wages are abysmal. Basically I work in a shop between 8 and 15 hours a week, more often than not the former. But my pregnancy is really interfering with it lately I can't concentrate and keep making mistakes so I feel it is in the best interests of the store and myself if I leave. Anyone been in a similar situation know what I could do.
