I had my period around July 12, me and my boyfriend has had protected sex about four times since that period but the last time the condom broke on August 7th and I took the plan b pill in 24 hours, I started spotting on August 11th and it was only for a couple days and really light. It's the 24th and still haven't had a regular period. Was that my period and I should have a regular one next month? Or what I need help?
