Thanks for asking this!
Lets talk a little bit about Plan B. Plan B is a type of Emergency Contraception.
Emergency Contraception is a hormonal emergency birth control method used to delay ovulation to reduce the risk of a pregnancy. The hormones delay ovulation– the process when the ovaries release an egg – and thicken cervical mucus.
Emergency Contraception can be taken up to 120 hours (5 days) after unprotected vaginal sex, but it is more effective the sooner it is taken.
A very common side effect of Emergency Contraception is a change in period. It can cause irregular spotting, or may jump start someone’s period. This is because it is a high dose of hormones.
The only way to know if you are pregnant is to take a test at least 14 days after the most recent sexual contact. You can trust the result at this time.
