The first day of my last period was July 28th and I had sex on August 7th.. The condom broke so I took plan b one step 30-40 minutes after the accident. 9 days after taking the pill , I started to bleed like a normal period at first it was a brown discharge but then it was normal. It lasted for 5 days. My period was supposed to come Aug 25 (today) but im not sure if that was my period or not. Should I worry? Did the pill work
