How long should implantation bleeding last

[Choc29]

Hi I've had spotting now for 4 days. Its only a small bit of blood and browner than my usual period. I was wondering if anyone else has had implantation bleeding last longer than 2-3 days. The Internet is giving me mixed answers about the time length. AF due Monday so still very early.

Oh my gosh I could have written this! Period due next Wednesday and I had very mild spotting (tinged mucus) since Wednesday just gone. So I thought it was maybe implantation but it’s carrying on longer than I would expect. I have had more cramps today and slightly more spotting so I think AF is on the way and maybe earlier?

Im just as confused as you OP!

Aww it's good to hear from someone else in same situation. I took a test today. I think it had an indent on it but I'm not sure. I'm now even more confused than ever lol. Xx

I have taken so many tests and all negative. I think if I have to use a flash light or stare at it in the window then it’s negative….yet I still check them this way 😂🤣. Stomach cramps are defo ramping up but means my period will be 5 days early which never happens so maybe it’s a chemical?
