What does implantation feel like?

I ovulated monday, baby danced sunday and monday. Wednesday i felt a weird pain on my left ovary. Then friday and Saturday i had the weirdest off and on pain. It was in my lower left pelvic area so low down! Felt like a pulling or tugging sensation ever few minutes and would go off and on throughout the day. I feel crazy but i have never felt this before, is this implantation or has anyone else felt this and know what its related to? Whatever it was, i felt it alot first I thought I was crazy but it continued for two days!
