Hi, I was just curious to why I had a regular 7 day period but it came 3 days late and blood reappeared two days after my finished period. The past three months my period came late by 10-14 days. This time it came 3 days late and lasted 7 days. What I wanted to know was to why I was begun to bleed again two days later that only lasted a day? (The blood appeared all on my underwear) I've had sexual intercourse a couple of times before my period but not during and after. I have felt bloated and cramps lately and have been craving heaps but my stomach hurts afterwards. Please help. Do I take a test to be sure ?
