In modern times contraceptive methods are really close to 100% and in most modern countries if that fails you can get an abortion that’s safe. Throughout mid evil Europe what did couples do. Would married women just keep having kids until they died? Ik there’s pulling out but sperm in pre cum so that doesn’t work. Also say a women was pregnant and didn’t want to be how would she get rid of it before giving birth if that was a option. And we’re any of those ways safe or effective to terminate.
Hello, I'll refer you to this question which has an excellent answer from /u/rainysounds about reproductive healthcare and a modest effort from me about circumstantial evidence for early medieval abortions and midwife figures in 10th century England that I hope you'll find useful.
Just as an FYI, it's "medieval".
