Patient's question:
I vaguely remember taking a short-acting birth control pill after my husband came home from work and we had sex last time, but somehow I got pregnant. I want to understand what's going on—how can someone get pregnant while taking a short-acting birth control pill?Doctor's answer:
The main use of short-term birth control pills is to start taking them on the third day of the menstrual cycle and continue for 21 pills. If there is a missed dose or if the medication is not taken by the specified date, it will not be effective for breastfeeding. Additionally, eating or drinking within two hours before or after taking the medication can also affect its efficacy. Moreover, if nausea occurs during the medication period, the effectiveness of the drug will be compromised.
