I have had pregnancy symptoms for weeks now. But I had a tubal 14 years ago. Could it just be hormones? I'm 36 years old and always have regular periods. Next one is due October 14 but have a light 3 day period & one dark blood period between my last period. What could it be?

It is possible, but before a missed period, there is normally no "pregnancy signs" missing the period is the first sign.

It is most likely other issues but you will have to wait to see

After 14 years it is possible, but not probable as scar tissue has built up around the area where you're tubes were tied.

However, it is possible that you might be beginning to enter perimenopause. That time of life that happens before menopause actually begins.
