8 dpo is rather early to be testing although, I've seen a few get their bfp's that early. Test again when you are at least 14 dpo. It's better to wait until after your period was due to test but if you can't wait that long try 12-14dpo....:)
I agree with Cnj and would also recommend waiting. Also when you go to test, use first morning urine. Anything else, especially when testing early is likely to be far too diluted to show an accurate test. Good luck and I hope this is it for you!
Thanks ladies I will. Appreciate the advice!
