I just had my period 2 weeks ago but now i'm bleeding again what could be the reason?

Can be normal: There can be variations in a woman's menstrual cycle that are considered normal and not to alarm about. If these changes become consistent and constant, then evaluation with a provider can shed some light on a problem.

Periods: Even woman with regular periods can experience irregularities at times, with your period coming either too early or too late. With that said, you should always test for pregnancy if you have an irregular period and are sexually active. Also, if this keeps happening, you should see your Family Doctor to get checked out for other medical reasons.
