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
