Bought a Pregnancy Test But Afraid of the response...

Im 7 days late, i didnt notice until i was like, its been a while since i had my period i should probably check eve, so i did and it told me im 7 days late. I went to the store and bought a cheap 88 cent test, which i bumped into my BEST FRIEND of all people there when walking around she didnt notice what i had in my basket, i had it faced down and kinda covered so she didnt really question it. But anyways, im scared of the results because if its positive i dont know if im ready to be a mom im only 17, i just turned 17. But if its negative im going to be a little bummed, im so conflicted but tomorrow morning im going to take the test, any tips on how to maybe deal with the results either way?
