Curiosity About baby kicking

Before i got pregnant, all the pregnant women i know told me about how they know exactly which body part of the baby uses to kick them...or they know the position how the baby is laying in their womb....i asked how do you know, they said "you just know"

but now i am 30 weeks pregnant, baby kicks very often and strong but i have no idea which body part she uses to kick me with... Lol or idk how her position is inside, i get curious all the time if anyone else really knows or they just guessing, or am i still too early to know?
