Ok ladies I am 35 years and had my tubes tied almost 10 years ago after my twins were born. I have 4 children 16, 11, and the twins 9. The boys are the youngest and will be 10 in May. I have been having symptoms that could either be pregnancy or AF. I am so stinking tired, nipple area is sore but not boobs, low back pain but not nearly like normal. Last period began 01/23/13 so I should start AF soon. If she doesn't visit would I be silly to take a test. I was told that it would be impossible to become pg again but I had a day of metallic taste in my mouth. I just feel silly even thinking I could be pg.
