Okay so i had unprotected sex on the 10th of Feb and like one or two days after that. On the 15th of Feb i started spotting like very like pink and than on the 16th and today its been a light brown, but only when i wipe (TMI i know sorry lol). Im not positive but i think my period should be coming maybe sometime this week or the next. Now my period is always like heavy as soon as it comes so i know that its not my period..Maybe implantation bleeding. I dont know..Im just kind of worried and hoping someone can let me know what they think. Thank You.
