oh goodness. plan b anyone?

Emmy
The condom broke around 11pm on the 5th. Woke up and took plan b around 8am on the 6th. Woke up to blood in the sheets Tuesday the 14th and bleeding was slow but mostly study up until about 4am this morning.. 
Any feedback on implantation bleeding or bleeding after plan b?
