So im not sure what is going on if someone could please help. I have a regular 30-31 day cycle on March 14 i got my period only lasted 3 days. Then on the 23 of march i started getting breast tenderness. I did have unprotected sex during this time and on April 6 i started having light spotting of brown discharge that lasted 3 days breasts are also not as tender but are tingly. Im not sure if this was early period or possible implantation bleeding. Any input would be appreciated
