Cut long story short , ive been glued to the back of a Carrera S the other morning at Autobahn speeds and ended up with this on my windscreen

Id like to try and repair it myself using a kit of eBay or something, the only problem is from what I understand to fix it id need to inject the special resin into it but the chip on my windscreen is pretty much smooth I can just about feel a little scratch on it , that's about it. Should I just leave it for now and see what happens ?
