Might be pregnant feeing really depressed about it

Weirdly enough I thought I couldn’t have kids for a while because of a miscarriage and now that I might be I’m feeling really guilty and depressed about it. I think I’d be a great mom but today at 3 I’ll find out if I am pregnant or not and it’s really hitting me hard that this is reality. Idk just needed to vent I guess. I’m not hoping for a negative or positive but if I am pregnant hoping for a healthy baby and if I’m not praying for my own health. I’ll be 18 in late May idk I just feel so sad 😞 not shameful but kinda just all hitting me at once that I might be pregnant. Anyone else felt this way?
