advise!

So I got my period two days ago, usually my nights are bad and I sleep with a pad on but I'll get up half we through the night and put a tampon in (since I don't like it in for all the long) so i was bleeding enough that I put a tampon in... this morning there was no blood and the tampon got stuck it was so dry!!! I quickly got out what I thought was everything (super early in the morning) and yes I do think it all came out 
Anyway!! How does a period just STOP out of no where and still no more bleeding!? 
Any advise???
