Hi Munchy
I am a very large lady also. I have endo and have just been told that I have Ashermans Syndrome.
Have you had a Laporoscopy or Hystorscopy??? to check the outside (for endo)and inside of the uterus. (If you had an infection in the uterus you also could have Ashermans Syndrome - which is scareing to the uterus walls - hence no preg). Something could be stopping you from getting preg

I was told once to loose 4-6kg to enhance chances to TTC.

I have had probs TTC and it can lead to me comfort eating (just can't keep away from those chippies).

I hope to be TTC soon after I have my Ashermans treated (it can cause M/C if I fall preg now). So I am trying to eat properly and do the exercise but am finding it hard because of the blues due to pain I am in most of the time.

Being preg and large dose have its down falls - not being able to see baby on u/s properly, high blood pressure which leads to pre eclampsia, just to name a few.
I even had the bad experience of a Rude Dr with a bad bedside manner .

Sending you lots of

Take care
Chris
