Hello, i just had my period about two weeks ago and now i had spotted for one day and it stop but im still cramping but no period...whats going on ???

Irregular vs implant: Irregular menses due anovulatory cycle is very common in young woman, albeit we debate regularly as to how young is young and how old is old. This should be less likely in 30s. It's quite possible that bleeding you noted might have been implantation. If/when you miss your period, take home pregnancy test. While waiting, consider OTC pain relief.
