I did something similar to what you did once-- but, I took a recommended dose. Please do NOT just take pills randomly again. There are websites that can tell you exactly how many of what type of pill you should take. Each pill is different, because each pill has differing amounts of hormones in it. You could have taken too many or not enough.
I would try to post a link to the site with all the pills and dosing information, but ehealthforum does not like it when I post outside links. Google "emergency contraception" and click on the princeton site. It has a complete guide on how to use your regular birth control pills as emergency contraception.
But, yes, your period will be very off track. You just ingested a large amount of hormones; your body has not received its "cue," or the placebo pills, which signal a drop in hormones and a withdrawal bleed. Instead, you took more hormones, so you may experience no bleeding at all for a while, spotting, or even what seems to be a regular period at an odd time (i.e., in the middle of your next pack).
I just have one question-- why did you take emergency contraception if you are on the birth control pills? When you say "unprotected sex," do you mean REALLY unprotected sex, as in no condoms, pills, or anything? Or just no condom? Sex while on birth control pills IS protected sex...
