Missed period.. My last peeiod started on 09/01/12 and lasted only 3 days. My next period was due 13/02/12 and 6 days beforehand I started bleeding which only lasted a day. Today, 05/03/12, I am currently 3 weeks late and started a very light flow. Today would be my ovulation day if I had had my period. I have been feeling nauseous, huge, tender breasts, mild cramping and exhausted all the time. I have taken 4 upt since the day of my missed period, all of which have come up negative. Am i holding a false hope of being pregnant? I m very confused.
