I am 46 years old and had a thyroidectomy over a year ago. I have not had a cycle since 12-3-07 and today is 1-24-08. I took an over the counter pregnancy test which came out negative. I am so blotted. Am I going through menopause or is there a possiblity that I could be pregnant and the urine test is not working or what is going on? Does anybody know?
