Pregnant or not pregnant

Hi there cuties

So I’ve got a big thing on my hands at the moment

I think it’s possible that I could be pregnant and i just turned 18

I’ll be able to tell this weekend if I am or not so I’m holding thumbs that I’m not because I’m truly not able to care for my own life let alone another’s is there any advice someone could give me for this or something similar you’ve gone through?
