pregnancy scare, absolutely terrified to test. need some advice

rose

I’m about 4 days late for my period and I plan on testing today just in case. I used a condom and pullout on the day after my last period, so I know my chances are low but my period isn’t showing any signs of signs of showing up. I typically have 30 day cycles yet I’m on CD. 35….. i need advice on how to calm down because im on the verge of puking at the thought of testing.
