What does implantation cramping feel like ??

Brittany • Mother to my little man . Wife to his wonderful daddy . 19 .
I'm either 6 or 7dpo . I had a pinching pain in my side and a lot of watery cm for the past three days . Now I'm having cramps like AF is fixing to show ! But I know I ovulated last week !!! But since this is my second post partum cycle I don't know how long it is .
