I had my periods on May 25th last month. I haven t got my periods yet. My regular period cycle is 26-28 days. I usually come 4 days early prior to my period date. So for this month I was expecting my periods between June 20-23rd. Today is June 26th. I did a pregnancy test yesterday and it came out negative. I never had late period. I m too worried! Am I pregnant?? Did I take test too early? What could be the reason.
