Implantation?

I have had kinda creamy Cm, when I Cm check I get a fair bit of white milky type of Cm on my finger, doesn’t feel to sticky but mostly like watery creamy Cm. But only when I Cm check, inside feels rather soft, and I can stick my finger up heaps high too.

Have had a bit of cramping now too, I’m about 6 dpo maybe a bit less, depending if I ovulated on cd14-15, or cd16.

Could be maybe start of implementation?

Like not to sure. Af doesn’t start till 30th:
