TTC 36 years old x2years

Ok so I don't get it NEVER in my life had I have tried so hard to get pregnant... We had a MC last Xmas and NO LUCK YET on conceiving. I am now taking the folic acid and prenatal's hoping that gives me an extra boost on trying to get pregnant... Do you think ladies that its my age that is keeping me from getting pregnant or wth os going on here??? Any input would be great... Thank you .🙄
