Hi, Jan 5th 2014 was when I started my period. My periods are usually 5-6 days.. they never come on exact date, it s either 5th of the month so WHAT IS MY CYCLE??? PLEASE HELP. Feb 5th I had maybe a 3-4 day light period. March 12th got a pregnancy test it was positive. Going by my lmp my due date is nov.12th but at my ultrasound changed my due date to Nov 9th stating that I was 15th 4days.. I m very confused, please help!!
