Am worried because my last menstrual was on Dec. 04th & my cycles are always on time. It was suppose to be here on the 3rd of Jan. & still no signs. I did a pregnancy test on the 5th & it came out negative but nothing yet. What worries me is that I had a tubal reversal on June 04,10 & only have one fallopian tube. What could be the problem? I just hope & wish I am pregnant....
