I went off the pill in February, and began tracking my periods in March. Last month I was 5 days late with spotting (I have never spotted before), but took it as stress. I was supposed to have my period 4 days ago (based on when I started my period last month), but still nothing. This past month hasn't been very stressful for me nor have I been sick so I am not sure why my period is late. I took a pregnancy test yesterday morning and it came out negative.
