Hello, I have a question about my period. I know this August was a long month so I understand why I got my period twice. My last period before this one was 7 days(normal) and started the 30th of July. Then, I started again the 20th of August. But it lasted 8 and a half days. Today, 4 days later, I start bleeding lightly. I get my birth control from Mexico and it's the shot. Well, this last time I administered it myself. And I had sex with my boyfriend a lot this past weekend when my tracker said I would be ovulating. I would like to know if it's implantation bleeding or if I should go to the doctor and get checked for something else entirely? Thank you
