Thank you for your question. It is very common for your period to be irregular after taking Plan B. As advertised, you may take Plan B up to 72 hours after your sexual encounter. Plan B interferes with the body’s production of progesterone necessary to sustain pregnancy which in turn may cause your hormones to be abnormal.
If you check this post, you will see that many women who have used Plan B in the past says it takes up to 6 months for them to resume normal periods. If you have any concern, you could obtain a pregnancy test to calm your fears.
