I have been on birth control for a year now. I started my period a week early this month and it only lasted 3 days. This has never happened before. Can me missing only 2 pills and then catching up cause my period to start and then stop 3 days later? HELP

It could also nullify the affects of the birthcontrol pill and leave you fertile for that month. It is a waiting game for now. Wait a few weeks for your period to come again. If it doesn't take a test two weeks after the missed date.
