ELI5: How did prostitutes manage contraception before modern methods?

And what did they do if they got pregnant?
gpt
There have been contraceptives for a very long time, the Egyptians used honey, and the Greeks used olive oil. The Greeks also used a specific plant for this very purpose that drove it to extinction, Silphium. As well as other methods, anal sex has always been popular with prostitutes, as well as knowing when they are ovulating to have the lowest chance of pregnancy.
