Patient's question:
I took birth control pills last month when I came to visit, but my period hasn't arrived this month yet. I'm worried that the birth control pills I took might not have had any effect on breastfeeding. Is it possible that my period hasn't arrived because I'm pregnant?Doctor's answer:
General emergency contraception pills have a very high success rate in breastfeeding, exceeding 98%. If your period hasn't arrived after delaying it by one week, you may want to consider going to the hospital for a check-up. Emergency contraception pills are not 100% effective, but they can also be successful in preventing pregnancy. If you don't get pregnant, you can take progesterone to induce menstruation. Generally, menstruation will return within 3 to 7 days after stopping the medication. You can keep track of your own menstrual cycle.
