History of infertility then became pregnant

Has anyone felt with infertility issues and then became unexpectedly pregnant naturally? I’m 40, I’ve dealt with infertility for years and the doctor said I had low ovarian reserve and poor egg quality. Went through three <a href="https://glowing.com/glow-fertility-program">IVF</a> cycles, no success because egg quality was bad. I have now randomly become naturally pregnant, which we thought would never even be a possibility. I am concerned because of the history I’ve had that I could run into issues with the pregnancy. Has anyone been in a similar situation and everything worked out fine? TIA
