Period lasted 9 days. normally 7. 5 days later i spotted brown that lasted 2-3 days. having slight cramping in left ovary. can i possible be pregnant?

Early pregnancy: It's possible. Home pregnancy tests are able to determine a pregnancy as early as six days before the first missed period. However, the "ovarian" pain could be an egg follicle rupturing into the abdomen - a common cause of pain at ovulation, which usually occurs at mid cycle, not during memstruation. Another possibilty is endometriosis. Your gynecologist can advise you.
