On August 27th I took a plan b pill because the night before, the condom broke & I just wanted to be safe. I started a period 3 days later (August 30th) that was a little lighter than usual & lasted 5 days (September 3rd) for the next two days I had spotting of old looking dark brown blood. That stopped until September 14th and 15th I had mucus like pink/brown discharge. By the 16th it was just dark brown stringy discharge that got heavier on the 17th and 18th. It started getting lighter on the 19th. All day on the 20th I didn't have a single drop until that night when I peed & a chunk of fresh looking blood came out when I wiped. Now it's the 21st & I'm back to this every couple hours getting a dark brown stringy discharge. Is this side effects from the pill? Can it be implantation bleeding? Is there a way to stop it? Please help!!
