I had a tube in 1997 and have one period a year is it cause I had my tubes fixed?

Tying your tubes. A tubal ligation should not change how many times a year you have a period. You should have a period at least every 3 months unless you are on certain medicines or in menopause. See your doctor.
No. Many stories still circulate about how tubal ligations cause irregular periods. Not true! Many women tend to get their tubes tied in their late 30s and early 40s; many women start to have abnormal periods in their late 30s and early 40s -- bam! Now the 2 get "tied" together! But...Not related at all.
