Hi, I am 42 years old and had a tubal ligation 16 years ago following the birth of my daughter. I have missed my last two periods and beginning the third month of no period again. I have had some signs of pregnancy such as frequent urination, bloating, fatigue, change in bowel habits, headaches, more emotional than usual, my stomach that was flat now has a bulge etc... I guess what I need to know is...what is the possibility that I could be pregnant? If not...what could be causing this? Thank you in advance for your help! Maybe Baybe?? Debbie K
