Missing Period & Low LH

Hello, I'm a regular reader of the hypothyroidism group on HU and wondered if you guys could help me out in this community.

I am a 23 year old female who hasn't had a period for nearly 1 year. Apart from this last year my periods always ran like clock work before (I started my period when I was 12, so that's 10 years of consistent periods)

This time last year I was training for the London marathon and after 3 months without a period I went to the doctors and they said it was due to the training.

In April I was diagnosed with an underactive thyroid (hypothyroidism) and again doctors said my lack of period was due to this.

I am now stable on my medication for my thyroid and feel the healithiest and fittest I have in months however still no period !! My doctor has told me not to worry but it's hard not to when I would love a family one day! It also feels unnatural to not have a period for so long.

I have had two sets of blood tests which I will post below, my LH level appears to be decreasing. I have the ranges for the different parts of the cycle however I am not having a cycle therefore don't know where I compare. I am being sent for more bloods in Jan including my LH level, FHS level and oestrogen.

If anyone can shed any light or give any advice on what I can do or not do then I would be so grateful!

May 2014 -

FSH = 5.0 U/L

LH = 1.7 U/L

Prolactin = 184 mu/L (range 59 - 619)

August 2014 -

FSH = 2.9 U/L

LH = 0.2 U/L

Prolactin = 146 mu/L (range 59 - 619)

  • Thanks for the reply. I'm still none the wiser :( been referred to an endocrinologist as still no period for over a year.
