Well im 39yrs old I have one daughter that's in her 20s, I was on birth control the majority of my twenties & been trying to conceive all of my 30s. Irregular periods, multiple medical tests (no signs of infertility Dr says) my only next step is to see a fertility specialist. I don't know what I'm doing wrong, my weight and exercise could be better but I honestly don't know & I'm ready to just give up!
