What happens if a woman keeps taking birth control throughout a pregnancy?
gpt
There is a slight increase to the chance of ectopic pregnancy.

There may be a slight increase to the risk of birth defects, but the testing required to confirm this will never be performed.

There have not been any studies into the effects of continuing into late pregnancy; But hormones play an important part in a pregnancy and there is no obvious reason to continue taking birth control. So it should not be taken.
