Twinges 1dpo...

I know... promise I’m not going crazy... honest... but I’m experiencing twinges 1dpo... is this something I need to worry about? I know im miles away from implantation but has anyone else experienced this and achieved a BFP? Is the twinging because my uterus is thickening ready for the next stage in my cycle or is it something sinister? What is my body trying to tell me? Thankyou in advance
