Late second period after taking Plan B? (7days late)

Hello,
I just went through the same experience, and spent time looking at message boards like this so I thought I'd let you know what happened to me. I had sex with my fiancé on September 21st and the condom broke. I took Plan B an hour later and got my period a few days earlier than expected on October 4th. I have a very regular cycle normally (28 days). I was due for my next period to begin on 11/1. My period did not come and I was very stressed because it was late. I experienced nausea, cramps, headache, fatigue and even sensitivity to smells. I was afraid I was pregnant. I took a few pregnancy tests and all came back negative, but still no period in sight. I finally got my period on 11/17, on day 44 of my cycle. It was VERY late. So try to relax. If you are nervous take a pregnancy test. Trust it if it's negative. I was anxious even after the negative results and was certain it must have been wrong. It was a whole lot of worry for nothing! It seems that plan b causing a late second period is very common.

Dear Anon,

Thanks for reaching out to EmpowHer today.

The most common side effect of an emergency contraceptive is changing the woman’s cycle. This can be stressful especially if it causes a late period on someone who is worried about being pregnant.

Here is a list of its side effects:
Side effects may include changes in your period, nausea, lower abdominal pain, fatigue, headache, dizziness and breast tenderness. Some women may have changes in their period, a heavier or lighter next period, or a period that is early or late.

I would suggest taking a pregnancy test, then going to the doctor and getting on regular birth control. EC should only be used in an emergency, not as birth control. Below is a link I'd like to share with you that will help.
