Hi Sharmin
I am so sorry to hear that. My mother too took years to have a baby: me . She had several miscarriages and after the operation of her uterus, she had me and continued with her miscarriages afterwards. When I got married, my husband wanted to wait for some years before trying for a baby but on that I was adamant(I was anticipating difficulties because of the problems my mother had), I wanted to try immediately so that if there would have been any problem, I would have years in front of me to go for all the possible solutions and I knew that it does take time. After one miscarriage, I was able to conceive for 2 consecutive times(thank God). . Afterwards I went to a gynae and she told me that it will be difficult to conceive with what I have . actually I have the same thing as my mother had: the uterus is not in its right position.
As it has been pointed out in other posts, it does take time with the different techniques. I believe that your friend should avoid telling her coworkers of her attempts, she will feel so down at those negative remarks. I can understand how she must feel when the test shows negative but she should not be discouraged. she must go for that with a positive mind and try to reduce her stress as much as possible. Fortunately there will be a good surprise in store for her. Give her a big hug.
Take care
