plan b causing late period ?

Okay, i had sex on july 4th, the next morning i took plan b and then took the second pill 12 hours later. my period came on the 12th of july, which was less than a week early, but it was regular and lasted 5 days. then i had my period in aug. 11th and lasted 4 days (it usually lasts anywhere from 3-6 days overall)and now its the 13th of sept. and it hasn't came yet. i've had all the symptoms i usually get. and i've read other posts on many different websites and they all say that plan b sometimes doesn't effect the period after you take the pill, but it does the one after that. i've been stressing out for the past 2 days and im not really sure what to believe or what to do. help??

Plan B can mess your period up for a few cycles while your body adjust. Plan B is a high dose contraceptive.
