Can plan b affect pregnancy?

Plan B is meant to prevent pregnancy, not end an existing one. If you're already pregnant, taking it won't do much other than maybe give you a headache. Take my advice, skip the self-medication cycle and just visit a doctor.

Plan B works by delaying ovulation to prevent pregnancy. If you are already pregnant, it has no effect on the fetus and will not cause an abortion. If your period is delayed, stop guessing and go get a beta-hCG blood test done.

I completely understand the panic when dealing with emergency pills, it makes you overthink every single symptom. Please know that Plan B won't harm an existing pregnancy or affect your future fertility. Try to stay calm and talk to a gynecologist to ease your mind.

According to gynecological guidelines, levonorgestrel (Plan B) works primarily by preventing or delaying ovulation. My doctor clearly explained that if implantation has already occurred, the pill is ineffective and will not affect the ongoing pregnancy or harm the baby.
