If you take the pill as prescribed, it is rare to get pregnant. However, it is not impossible. The hormones in the pill do not affect hCG levels, which is the hormone that urine pregnancy tests look for. You can schedule an appointment for an accurate laboratory quality test with us. Once you learn you’re pregnant, stop taking the birth control pill. There’s very little evidence that exposure to the hormones in birth control pills causes birth defects.
Contact the prescribing physician for guidance on continuing the pill and your pregnancy.
