Should I take ECP? Or am safe

My fiance and I never had sex before and last night we just inserted the penis tip like 2,3 times only . That’s how much it was in. However, it was raw no condoms and I am also not on birth control. Also, he did not ejaculate and no precum as far as i think.

I wanted to ask should I take ECP?? Or birth control. Is it possible for me to get pregnant. My period cycle says my ovulation is 5 days after .

Am freaking out
