Abdominal Feelings

Hi all! Question...

It’s been 5 DPO and I haven’t experienced any implantation bleeding yet (hopefully soon), but I have been feeling tiny stretchy-like feelings on one side and then it would go away and then soon it would be in the middle for a bit. It’s definitely not cramping because I know what that feelings like😟

Is that a sign of implantation or just my body getting ready for a period?

I’m new to this so not sure! Any feedback would be appreciated! Thanks
