Help please

So today I got up to go use the bath room . when I got up I felt a slight rush so I go check ,I had a pad on because I thought my period was starting I had little cramping nothing major , my period doesn't start til the 5th of July ,but anywho I look and there was blood but it was super light . and it was like watery . like I said my period doesn't start til July 5 . does anybody know or has this happen to anyone before I'm ,not bleed at all now ,no little cramps nothing
