What brings you in today?
Explanation
Taking birth control pills during pregnancy is not usually linked to birth defects. Studies have looked into this and found no strong evidence that these pills cause problems for the baby.
Some studies suggest that using oral contraceptives in pregnancy does not significantly increase the risk of major birth defects. Research also indicates there is no clear connection between birth control pills and birth defects. While the possibility of limb deformities has been examined, a strong link has not been established.
Even though these studies show that taking birth control pills by mistake when pregnant is not likely to harm the baby, it is still best to stop taking them once you know you are pregnant. If you have any concerns about pregnancy and medications, it is always a good idea to talk to a healthcare professional.
