Am I Pregnant Even Though I Took Plan B?

Long story short, I'm not on birth control and after having sex with my boyfriend, we noticed the condom broke. I took Plan B 20 hours after the incident and had a "period" two days later. The period was normal flow/duration, but it was two weeks early. I haven't got my period since then and it's been almost three months. I get cramps every now and then but that's it. I took a pregnancy test a few weeks ago and it was negative, but I peed on the window a bit so I'm not sure if it foiled the test. The test was Clear Blue though, so I'm not sure if that makes a difference. Any thoughts? I'm panicking a bit.

Hi Anon,

Thank you for being a part of the EmpowHER community and sharing your question.

Plan B / Emergency contraceptive pills will affect or delay a woman's bleeding pattern, however, since you haven't had your menstrual cycle in 3 months, you could be pregnant.

  • If you taken within 72 hours after unprotected sex, Plan B One Step can reduce the risk of pregnancy by up to 89%
  • Taken within 24 hours, it is about 95% effective.

Since you have already taken a home pregnancy test, and even though negative, I would have your doctor give you a more sensitive pregnancy test.

If you are not pregnant, then you and your doctor can explore reasons why your menstrual cycle is abnormal.

I hope this helps,

Be well,
