Implantation bleeeing

[Kammie22]

Hi im looking for anyone's advice on implantation bleeding, I had some brown spotting yesterday evening and woke up during the night with usual af pains and bleeding, so i assumed I was out however bleeding is back to spotting tonight, I wasnt expecting AF till the weekend going by my previous 2 cycles and af usually lasts 4 -5 days. I'm just wondering if anyone has experienced what they thought was their normal period bit turned out to be implantation x
