I would say it makes it pretty ineffective and you aren't safe and weren't when this occurred if you had sex. I would say to use back up birth control until you have taken the pill consistently for a cycle. In terms, of pregnancy that may have occurred, you can test 2.5 weeks after the last time you had intercourse. Your period kind of indicates you probably didn't but you need to do something to remember taking your pill. good luck and please let me know what happens!
