What am i doing wrong?!

Im slowly giving up on this whole TTC. I am now in my 6 year of trying. Im sick of hearing 'your time will come, when its right', most of the people who say that got pregnant first time round. I just want to have a family now. Me and my husband are both ready to become parents, we want nothing more. We both mourn our first baby we lost, we even have the furniture ready to build for our rainbow baby.

But i just feel like its never going happen. My AF was meant to show today, i took a test this morning and its still a BFN?! Im so upset.

Im losing weight slowly, I eat healthy, I exercise regularly, have an amazing active sex life.... am i just not meant to be mum?
