Sex on fertile day...advice?

Soooo I just had sex with my boyfriend for the second time ever and the app says I have a 33% chance of pregnancy... we used a condom and he didn't cum inside but at the same time we want to be extra safe incase some precum slid out?

Should I take an emergency pill or is it not worth it?

If I do will there be any side effects?

(I sadly can't talk to a doctor about this in my country because abortion and sex before marriage are extremely contraversial)
