I had my tubes tied 3 years ago and I have always been like clockwork on starting my period. Same day, almost the same time(night time) for as long as I can remember. I am now 6 days late, two days ago I took a pregnancy test and it was negative. I figure if I don't start by monday(4 days) then I will go to my Dr. I just don't want to look silly. Is it poss. To get pregnant? I have never used protection with my husband because I just assumed I was protected, but now I am getting worried. Would a tubal pregnancy show up on a home pregnancy test? I was also told I had a fybroid tumor on my uterus.....Still small, but that was 5 months ago. Could that have anything to do with it. Anyway, no weight gain or weight loss, no change in medicine, no change in stress, no tenderness anywhere, hmmmm.... Am I just worried for nothing?
