HI, I am 31 years old and had a tubal ligation ( I think they clamped or used the rubber bands ) 2 years ago when I had a c section with my son. I am still b/f my son and my periods returned normally and have been for the last year. My last period was on the 13th April 2013 and I normally have a 32 day cycle. I feel uncomfortable in my pelvis area and have that full bloated feeling so conducted a home pregnancy test which has come back negative. Normally I would expect to see my period return by now. Is it possible for me to become pregnant even though I have had a tubal ligation?
