Self employed mamas

I’m a hairdresser and planning to take 2-3 months off if possible I’m just freaking out about how I’m going to be able to afford doing that. I don’t have a major savings and didn’t plan ahead for maternity leave. I wish there was a way I could generate income at home somehow. I don’t want to spend the first few months with my baby stressing over making ends meet. Anyone have any advice?
