Period one time but only lasted one day? HELP

HI all,

So yesterday my period arrived as expexted;right on schedule. My period usually lasts 5-7 days,it is usually very heavy, abd I suffer from bad pains and vomiting. 

However, my period has now disappeared. So it literally lasted one evening and was extremely and was light browny/pink. Very very confused ATM. has anyone ever experienced this? Haven't done a test yet as I'm fed up with negative results lol
