Help!! Brown discharge!

[Rae176]

I am currently 4w+2 and have just gone to the toilet and on the tissue was brown discharge! I am so worried as I have had a miscarriage in the past! It is around the time I should be on and have ready that it could be spotting/implantation bleeding, just wanting some advise.. thankyou in advance :)

I had brown spotting between 3 weeks 5 ish and 4 weeks 5 ish. It must have been implantation bleeding as im now just under 6 weeks x
