I had a 3 day period on april 26 and i always have a 5 day. it was on time but not normal. could this be a sign of pregnancy? i also had cramping

Pregnancy test : If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy. Seems like it will likely be negative since you had your period

HPT: The main reason for light periods is a change in hormone levels. Causes for what seems to be a light period can include: implantation bleeding in early pregnancy, thyroid problems, eating disorders, excessive exercise, initial periods for a girl, use of an intrauterine device, oral contraceptives & perimenopause. If you aren't sure if this was your period than you can take a home pregnancy test.
