DD took 8 months to conceive at age 35. I have just turned 40 and been trying for 18 months without any joy. We have been tested and there is nothing medically stopping us. I use Ovia to track everything, use the Clear Blue ovulation tests which are supposed to give you a 4 day window, we DTD every 2 days and increase to every day when the smiley faces tell us, I am a healthy weight and get exercise and have a reasonable diet. The only supplement I take is the Seven Seas trying for a baby one. I gave up alcohol and caffeine at the beginning but am drinking both again as abstaining didn't seem to help. We have agreed that we will try for 2 more months and then call it a day as that would mean that i would still be 40 when I gave birth (but this may get extended to the end of the year so we've given it 2 years). Prepared to try anything at this point - anyone got any tips of things that helped you conceive naturally at a later age? Thanks in hope
