Pregnancy symptom at 7dpo??

Brittany • Mother to my little man . Wife to his wonderful daddy . 19 .
I know cm isn't a very accurate way to detect a pregnancy seeing as how it varies woman to woman . But I'm thinking im 7days past ovulation . And having so much watery cm .  And mild cramping . It feels kinda like a pinching pain in my side not like typical AF feel like ??
