Think I'm implanting...

So I started cramping slightly yesterday afternoon it went away so I thought it was gas. Then today I started cramping again but more consistently but not as bad as period cramps more mild. It feels like the last time I got pregnant but I don't know. So last time I had what I thought was implantation cramping for 2 days according to my logs on my apps and then I tested positive the next day is that possible?!?! Or maybe I implanted sooner but just now feel the baby burrowing?! Idk. Should I test tomorrow because this is almost identical to the last. AF not due til 29th 🙀
