My period was 5 days late. The prior week I was having cramps and kept running to the bathroom but nothing, then they just went away. I was having mild headaches that I usally never get either. I took a test and it came out negative then the next day I got my period. My periods usually have heavy cramping and heavy flow but not this time. I started the morning of the 21st and today is the 23rd afternoon. I have only used 1 pad per day...and maybe had to change 1 the first night, now it's over. My periods usually last 4-7 days. I am confused because I have some cramping and bleeding, test was negative but I just feel something is off. Could I be pregnant?
