Possible Pregnancy After Tubal Ligation: Symptoms & Ultrasound Results

Question
I am 27 years old, I have had 3 children and my LMP was sept 15,2005.  Ok before I start, I had my tubes tied in dec 2004 during my c-section following the stillborn birth of my son.  I had several positive pregnancy tests in July including 3 in my dr's office.  I did bleed for 2 days after my period for july was 10 days late.  I had a bloodtest on 7-20 and she said the numbers were so low it was like nothing was there, I had an u/s 7-29 and no sac was seen.  My question is was this possibly a chemical pregnancy, is it possible one of my tubes might have reconnected?  

Answer
I doubt that your tubs have reconnected. If the blood test showed a value of less than 5, you are definitely not pregnant. Perhaps the urine tests were incorrect. Since the blood test is negative and the sonogram does not show a sac, you are not pregnant.
