Feeling bummed

I’m feeling a little down. I have been TTC for only two months and still haven’t gotten pregnant I feel like I’m doing everything I can. I know there is some women who take up to a year but my first baby I wasn’t even trying and I got pregnant right way. My second one again not even trying then I had a miscarriage and I waited a year like they recommend and I thought after having a miscarriage it would be easier but I guess not. I’m only 27 is it normal to be having difficulty getting pregnant at this age?
