Back pain, dull pelvic discomfort

Period just ended today. Had sex plenty of times before it & once while on it. Is it common to have period exiting symptoms? Lol my body was achy then just my back but my pelvic area had “pain” all day, even a burning sensation at one point. My last pap was 2 months ago, so i dont have any cysts or issues. Cycle is normal.
