Weird period

Sharicka
So I got my period twice in one month (01/03/16-01/07/16 and 01/29/16-02/02/16) and I have missed my period for this month" February". I have never had two periods in one month, the period that came on on 01/29/16 started off light brown then it was brown with some blood and at the end of the period it changed back to the brown color
