Plan B

On June 14th I had sex for the first time. I took Plan B 4 hours after and five says after I bled for maybe 4 days because of the pill. Saturday, on July 9th I had sex again and the condom broke so of course I took the pill again. Between these times I didn't have my period because it usually starts on the 9th... Or around that time. Well on the 9th it didn't start. Should I be worried?? And if I bleed would I consider it the pill or my period?
