My cycle falls around 28-31 days. My period last March came early which makes my cycle 25 days. Last April it became 23 days. On May 2, we again had intercourse. And now I'm 16 days late. Last week i took pregnancy test (first pee in the morning), it was negative.6 days ago, i took blood test it was also negative. I'm not experiencing any change in me. Am I pregnant or do I have other sickness? Because I used to overthink things even if I am only 2 days late before. Everymonth before my period comes I used to do excessive exercises and even punch my lower abdomen so hard in order to induce my period. This May was so late so I did more excessive exercises and lift heavy things and punch my lower abdomen more.
