Hi guys, just need to ask something. I just noticed my windscreen got a small crack. Didn't even realize when/how it cracked until it rained one day, and due to the crack got bulge a bit, it made loud noise when wiper wiped on it. And after a while, my wiper got damaged a bit because the crack is quite sharp and it tore the wiper a bit. Below are the pictures:


Just want to ask, do I need to be worried if the crack is this small? ie will it spread later and endanger me if I don't replace it now? If I replace it now, how much will it cost? I passed my 10k service already, and I also didn't take windscreen insurance, so, need to pay this myself if I replaced it
Thanks!
