Implantation?

Luisa • Mommy to a baby boy 💙 baby #2 coming July 2019 😍

I’ve been having mild cramps on the lower left side of my tummy kind of like a pulling sensation and tingling also feel pressures down I’m kinda sore on the lower left side been feeling nauseous as well. This has been going on for 3 days now! could that be implantation? AF comes in 7 days so I know it’s not period cramps!
