TMI-is diarrhoea a sign of implantation?

I'm 7DPO and feel fine in myself but today had 2 episodes of diarrhoea where Iv needed to urgently go to the toilet 🙈 10 months TTC and BD quite a lot last week, just wondering if anyone else has had this and got a BFP? AF isn't due for another 8 days and haven't eaten anything that could cause this so just wondering if this could be a sign? TIA
