Irregular period!!! Help!!

Ashley
Okay.. So I ended my normal period on the 15th. It was heavy and I had normal period cramps.. Then I started again on the 24th which I shouldn't have started until 18 days later.. I had minor cramps the first day.. I am wondering if I could be miscarrying because I'm bleeding way more then normal.. I'm not having any bad cramps or anything but the last three days I've woked up I've been soaked through my tampon and panty liner onto my thighs.. I'm never this heavy.. There is no clumps or anything.. Can anyone give me input?
