Oh Emma - you are really not getting a good deal on this. Do see you GP and complain.
It took me ages to conceive my first baby - I was 30 at the time. In the end I borrowed the money off my mother to see a specialist who did some tests - my husband had to have a sperm test as well and this is quite important as it may not be you that has the problem!!?? From the start of trying for the baby to conception was 18 months for me.
If the blood tests are done at the right time it will show whether you are ovulating which is the most important thing. Anyway, my husband and I had all these tests done and then I found I was pregnant!!! There was nothing wrong, it just took time to conceive - maybe having the reassurance that all was basically ok helped me to fall pregnant. A year after my first baby we tried for a second and I fell pregnant almost immediately!!!
I am the only one of three daughters who has been able to have her own babies. My older sister had to adopt and my younger sister went through several heart breaking rounds of IVF and ended up adopting.
I really understand how you are feeling, I was a crying mess every month when my period came.
The mind does play games and if you focus too much this can get in the way. So if you can get on with enjoying your life, still try to see a specialist, look after your diet and exercise regime to keep really fit and ready - then hopefully that baby will come to you. Good luck Dg x
