Hi,
Welcome to the ehealthforum. I am glad to help you out.
Pregnancy definitely needs to be ruled out in your case as you havenât had your periods, although you have had your tubes tied.
Pregnancy can be ruled out by doing urine for pregnancy test and also getting an ultrasound of uterus done.
The ultrasound will not only help in ruling out the pregnancy but also look for the other causes of the delayed periods.
The common causes of the delayed periods are hormonal imbalance, increased stress, eating disorder, smoking, alcohol or caffeine use and medical conditions like PCOS, fibroid, polyps and endometriosis. Please do consult a gynaecologist for the same.
I sincerely hope this information helps. Take care.
