Throbbing pain on left side of uterus

KJM • Hospitality Industry Professional, Mom of One, Still Figuring Out Life

NOT OVARY, i have this throbbing sensation in my uterus kinda towards the left frontal side. It felt like gas & uncomfortable last night now it's just this occasional throbbing feeling that's still uncomfortable & i'm not sure what could cause it. I know what ovulation pains feel like & this isnt it & i'm not supposed to ovulate as i'm on nexplanon. Any ideas?
