Happen To Anyone Else??

Jaimee Tuttle ttc baby#2💕

I'm 6dpo today and was completely fine this morning. As soon as noon 12:30 hit, my back all of sudden felt like it was split in half!!😩 My whole lower back feels like pulling and tightness. Has this ever happen to anyone while ttc during the TTW? I'm hoping this is could be implantation pain🤞🏼But dang I know I didn't pull my back muscles 😭
