Lighting pain 6 weeks help

Kr

I'm 6 weeks and 3 days and when I wear anything tight around my waist I get this pain in my left side thats where the body is growing aswell and I'm wondering why like the clothes don't even have to be to tight like I could be wearing stretchy boxers shorts and the lighting strikes in my abdomen or maybe it's not the tight clothes maybe its because I'm cleaning or doing too much around the house idk but dose this happened to anyone else this early on in pregnancy 😩
