Help please

So there’s a small chance im pregnant (there was a low chance of pregnancy in my cycle for the day it happened)

If I am im a week in

I don’t normally get sore or bigger breasts before a period but they’re sore right now and my period is due in 2-3 days,

Ive got an appointment to get birth control in 7 days

I do not want to be pregnant right now as I’m under 16

I’ve been having a lot of papayas and pineapples (they’re known for stopping pregnancies) and I’ve also been having hot water bottles and hot baths

Any way of finding out if I’m pregnant (not using pregnancy tests because I can’t get one) and stopping It ?
