hello, I had my tubal ligation back in april of 2002 and also regret it... been married for 6 years and have no children together. I have been having all the symptoms of pregnancy, bloating, breasts hurt and ache, nipples tender and sore, sick to my stomach, vomiting, tiredness, pelvic pain and pressure, cravings and so on...took 2 urine tests, and also a blood test but all came back negative. went to docters and had an internal exam and he said that my cervix is fine but my uterus is enlarged. going for an ultra-sound on monday. hope its a baby and nothing else.. kinda worried. does anyone else know what this could mean?
