Implantation symptoms

Has anyone every felt a pulling sensation? I feel a strong pulling sensation on my left side. I usually feel a pressure on my left side (I’ve been checked multiple times and I’m told it nothing), but this is completely different. Also, my thighs hurt. Random cramping to the right side.

Honestly, I hate symptom spotting. It drives me insane. I’m 5/6DPO. Received a peak OPK last Friday at noon.
