I started my period weekly early I have heard it's very common to happen I had no signs of period coming normally I get cramp so anyway started off I had sex had spotted blood I put down to haven't had sex in long time so maybe had effect then had normal discharge with tingly feeling in viagina then started light pink spotting day one day two was more deep red heavier I had this last three days and now it's stopped.I do know can have early periods but the cramps started last two days so like my body clock all over then I feel full and smells knocking me sick so just need advise is this implantion bleeding or is it early period or could be something more serious
