Hi I m 42 years old. 1 week after my period last month I had menstrual cramps and the next morning woke up spotting brown. The next day woke up and had light pink spotting then stopped. I figured it had to do with ovulation. This month I m 6 days late. 11 years ago I had a tubal ligation during my c section procedure. I took a pregnancy test (urine) and negative. I have a slight discomfort in my left lower abdomen. Can I be pregnant?
