In need of some positive TTC stories 😔

Ladies.. been with my fiancé 17 months. Never used contraception or birth control. And never got pregnant.. we decided we would try TTC actively a couple weeks ago so downloaded this app in hopes of understanding about ovulation and the right times to have sex... I’m just so scared I won’t get pregnant 😔😔 been BDing like crazy this week because it says it’s my fertile window until Sunday. I’m just really In need of some positive success stories after TTC for more than a year.. even tho haven’t been actively trying for the entire 17 months. Any support/advice/positivity would be really appreciated ladies! And baby dust to all of you ❤️❤️❤️❤️❤️
