Period After Plan B

Ashton

Long story short: I was having sex and the condom broke so my boyfriend (at the time) immediately ran to CVS and bought me Plan B. I took it less than 3 hours after the incident.

I bled ridiculously heavy for 2 straight weeks after.

It is now time for my period and I am 4 days late. I can imagine the 2 weeks of bleeding is throwing this off, but should I be worried?
