I feel so disappointed ttc since July last year

My doctor was no help today. Basically says if not pregnant in two years then come back could try ifv or something

How can my period lengths be normal i have spina bifida 35 two miscarriages. But my doctor say well at least we know you ovulate. No blood test were taken. I know some people ttc a hell of a lot longer than me. But i just feel like it's never going to happen. My transplant nurse said last month now best time ttc as kidney transplant working great. & she also said last month doctor should help but it seems she was wrong. I honestly don't know if i should give up be motherless or get a second opinion that's what my boyfriend wants to do second opinion
