Advice and help?

I’m 34 and trying to get pregnant with our second child. When trying to have our daughter I had just went off birth control and it took about 9 months. Now we are experiencing secondary infertility. This is my 13th cycle of TTC. Today I was hoping my 3rd round of clomid worked but got a negative pregnancy test today. I’m thinking of going off of it. The doctors said I was ovulating before I tried clomid. So that’s not my issue. Any suggestions or advice?
