lump on left side of stomach/ pelvis | pls help

for the past week, i’ve been having pain on my left side of stomach / pelvis and naturally, i would push down my fingers onto the side (idk why, i just do). this time when i’ve done, i’ve felt something hard like a lump but i’m not sure if it’s actually a lump or if im just imagining things since i can’t feel anything on the right side.

not sure if this is helpful but i had surgery back in 2019 to look for endo and all they have is lumps and my uterus was inflamed (whether that is endo or not, idk) so not sure if that has to do with anything
