Cramps After Sex/Orgasm

since i’ve been pregnant, i get these semi-intense cramps immediately after intercourse and they’re even worse if i orgasm. it’s to the point they make me sick to my stomach 😪 i can barely enjoy that time laying with my boyfriend afterwards, im just so uncomfortable & it takes away from the enjoyment we just shared..i know this is normal, but does anyone have any tips or tricks to avoid them altogether or at least to ease them a little? i’m kinda struggling 😫
