Hi Laura,
Firstly – well done you! Its not easy going it alone and it takes courage – so remember that.
Secondly – you are not a failure! Infertility is diagnosed by the World Health Organisation as a disease. So you have not failed – you are suffering with a medical problem, like many people where it may take longer and need medical intervention to help – you have not failed at anything.
We do say that you should test on official test day as I have seen many women who have had negatives that have turned into positive tests on test day. The scientific reason for this, is simply that we cannot predict exactly when implantation takes place – so we estimate when it should be but it can take longer sometimes.
Please reach out with any questions you might have – we are here to help and support.
Take care,
