Trying to conceive or gods fate ?

This month Me and my partner have been trying to have a baby and I’ve been on this app obsessively waiting for it to somehow be the one to tell me I’m pregnant based off other people’s experiences. But i keep reading people’s post about how long they’ve been trying to conceive as if it’s in their power.

-my sister who has had multiple doctors tell her she wasn’t going to be able to have children has had 2 unexpected healthy pregnancies.

So don’t you think if it was up to us we’d get pregnant because that’s what a woman’s body is meant to do ..?

Maybe I’ve found myself jaded because here i find myself trying to conceive like many of you and scared that it won’t happen .. but is that gods fate or that now suddenly i won’t be able to have more children due to health reasons ? - just late night thoughts hopefully no one finds this offensive
