Hello, and I hope I can help you today.
Having your fallopian tubes "tied", or having a
tubal ligation, whether it is done by burning, cutting or tying suture around the midportion of the fallopian tube results in permanent
sterilization. The reason for this is that a portion of the middle of the fallopian tube dies or is scarred permanently from the procedure, no matter how it is done.
The overall failure rate for tubal ligation is around 1 in 2000 over a women's lifetime, however most pregnancies after tubal ligation occur in women within 2 years of their operation, or in women under the age of 30.
At this point in your life, it is a much greater chance that your period is delayed due to
hormonal issues rather than
pregnancy. I do recommend you perform a pregnancy test just in case, and if it is positive, you should seek medical care right away as it is very likely that you have a pregnancy within your fallopian tube (called an ectopic pregnancy) which is a medical emergency.
I hope I was able to adequtely answer your question today and that my advice was helpful.
Best wishes,
Dr. Brown
