Comments are much appreciated

I’m three days after getting fingered by my boyfriend. However, he did adjust himself (he had underwear on though) before fingering me. No sex no ejaculation. However ovulation was two days ago.... i have somewhat sensitive nipples now 3 days after intimacy. Only when i pinch them they hurt a little idk if they have always been like that or if I’m just noticing it now cuz I’m scared of pregnancy
