Can Plan B Mess Up Your Cycle?

Posted on Tue, 5 Jun 2018

Question: Around the week of October 20th I took plan b (emergency contraception) 2 times. A couple days after the second time (maybe around 10/26) I got a short period, I have not had a period since, can this contraception mess my cycle up that much? Up until then i had a normal cycle, of course I havebeenstressing worrying about it but I have taken many pregnancy tests up until yesterday and all are negative. I just can't beleive it's been two months with no period this hasn't happened before after taking it.

Hi
Welcome to healthcare magic. I amDr Ramadevi Wani. I will be answering your concerns today.

Plan B can mess up the cycle sometimes. In addition stress also can cause hormonal imbalance and result in irregular cycles.
If all your pregnancy tests are negative, there is no reason to worry. However take a blood pregnancy test to be 100% certain that there is no pregnancy. If that is negative, discuss with your doctor and take progesterone for withdrawal bleeding.

Once you get your mensus it is better to plan for using contraception.
I hope this is helpful. If you have further concerns, I will be happy to answer.

Welcome back.
Progesterone can initiate menstrual bleeding if one is not pregnant. Bleeding initiated by progesterone is called withdrawal bleeding.
