Cramps and other stuff TMI

Okay so I’m currently 5dpo and I had the worst cramps today it not like period cramps they were more burning sensation with each cramp and I constantly had to go do #2 but I didn’t eat anything out of the ordinary and I’m not sick or anything my stomach doesn’t feel upset I don’t feel nauseous the pain is like in my uterus more to the left than right the sensation of cramps and aching is there but when ever I have to go it worsens 🤔 any thoughts?
