in 2011 I had a tubal ligation, clamps only. My period is 10 days late, took a pregnancy test and was negative. Had light pink spotting and menstrual cramping after intercourse that lasted less than 12 hours. Now 2 days later I am spotting again, very crampy and nauseous with slight back pain also I have a hazy cloudy feeling. Could it be an ectopic pregnancy? Oh, I am 34 years old.
