When someone starts a new hormonal method of birth control, they need to use a back up method (like condoms or practicing abstinence) for one week before that method will be effective. After that first week, the hormones will be integrated into the body and can help prevent pregnancy up to 99% when taken correctly.
If you had unprotected sex (meaning you didn’t use a barrier method like a condom) only 3 days into your pack of pills, you will be at risk of pregnancy.
You have the option of taking Plan B (also known as emergency contraception) up to 5 days after unprotected sex. The sooner you take Plan B, the more effective it will be. The hormones in Plan B prevent ovulation – the process when the ovaries release an egg – and thicken cervical mucus. Plan B is not an abortion pill. It will not harm or end a pregnancy; it will only work to prevent a pregnancy.
You can also take a pregnancy test 14 days after unprotected sex to get an accurate result. Teen Clinic offers Plan B and pregnancy tests on a confidential and free or low-cost basis. Give us a call with any questions you may have! 303-442-5160.
