Woke up from a nap and felt like I had the start of period cramps 9 dpo

when i woke up from my nap my tummy felt crampy and last couple of hours it feels bubbly. I keep feeling like I have to use the restroom but already went twice. Hopefully this is implantation cramps! I ate pineaplle with the core for 7 days and used a Moxa stick which is an ancient chinese stick my friend gave me to light and move over your belly to promote healthy blood flow to reproductive organs. wondering if I should burn the moxa stick today too 😊. She feels it helped her embryo stick
