I took plan b on July 2nd, two days after me and my boyfriend has sex. later on July 7th I got brown spotting which turned heavy and red, like my period. It lasted 3 days. My period wasn't due till July 20.
Then on July 11 me and my boyfriend grinded with no clothes on but he used a condom.
On July 17 I got brown spotting but it was very light. It continued to the next day but got lighter, and now my period is due. I don't know if this is a side effect from the plan b again or implantation bleeding. Please help ASAP!!! thank you
