I just started birth control 3 days ago and the condom broke, so should i take plan b with my current birth control? quasense birth control

Yes, : Yes, please take Plan B to be on the safe side. Also please contact your prescriber of birth control pills and let them know about this.

BC failure: You have only been on Quasense for 3 days (See: https://www.drugs.com/pro/quasense.html) and had a failure with the condom - so an emergency contraceptive would be in order. Plan B One-Step can reduce your risk of pregnancy by up to 95% if used within 24 hours of sex. If taken within 72 hours it can reduce risk of pregnancy by up to 89%.
