Feel like I’m never going to get pregnant again

Good morning ladies, I am 36 years old I’ve never had trouble getting or staying pregnant. We have been trying for 8 months to get pregnant last cycle we did get pregnant but unfortunately it ended in a chemical pregnancy. So after getting the go ahead from the doctor we are trying again. But I feel like I was lucky last cycle and I’m not going to see another positive pregnancy test again. Does anyone else feel like this?
