Implantation bleeding

How many of you have experienced implantation bleeding (IB). If you have, how many of you got a BFP 4-8 days later. How many of you were disappointed and got a BFN 4-8 days later. Implantaion bleeding (IB) can be one of the first signs of conceiving. I've experienced implantation bleeding back in April, but then was extremely disappointed with a BFN and AF. Now yesterday i also had what i think was implantation bleeding. Unfortunately, I am holding myself back from getting too excited because im afraid that again this will not be the begining of my journey to motherhood. Who else has experienced this?
