Hello iam 17 and I recently have lost my virginity in January and that month my period came as normal then in february my period had come a whole week early. Which I just assumed it could have been from stress. I had been having unprotected sex through January till February 11th. The last time I had sex was february 11th and today is march 13th and I had just started bleeding around maybe 6 or 7 pm on march 12th but there was barely any blood at all and that's not normal for me my periods are usually heavy and dont start out with light bleeding either but my bleeding is still going but there's still barely any blood on my pad. The blood is a really light reddish pink. So I'm not sure if I'm actually having implantation bleeding cause it seems a little late for that or if my cycle has just changed from having sex. Please help!
