Your obviously irresponsible to be manipulating your birth control like that. Those are artificial hormones and that can wreak havoc on your endocrine system and cause all kinds of chaos later on ... and now. You need to obviously call a poison control center and then call your doctor just to be on the safe side.
It's not great that you had to take them all at once. It's not going to kill you (e.g. morning-after pills are often high dose hormone pills, and there are certain pill brands that you can actually use as an emergency morning-after pill by taking several ****), but yes you will definitely feel sick from it.
There is a little pamphlet that usually comes with pill packs that tells you how to take your pills if you miss any. Different brands of pills can have different 'missed-pill' schedules - they often have this information on the brand's website as well. Most will tell you to take your missed pill as soon as you remember even if that means taking two at once -- but I'm not sure if they would suggest you take three at once.
I would wait until tomorrow to take today's pill. Four pills in one day is definitely overdoing it. Use a backup form of contraception (condoms) for the rest of the month.
(**** not all brands of pills can be used like this, it depends on the type and concentration of hormones)
