Pregnant and not tracking

Hi everyone!

As anyone who usually tracks ovulation and stuff gotten pregnant when they havent? I know this is a silly question. Im just genuinely curious if the stress of tracking can prevent it happening more.

I was tracking the first 2 months and spending heaps $$ of ovulation tests and nothing.

This month I have had some money issues and cant afford $50 just for ovulation tests when pregnancy tests are also expensive. I havent tracked bbt either, just being BD and butt up after. But im worried again stress will prevent it.

In the last few weeks, i have lost a beloved friend, money benefits got cut, family and friend issues etc and this month is my bday and xmas month which means more moneu to be spent and obviously preparing for xmas day, but im wondering if stress is the thing to stop it happening? Im nearly 23 so im still young
