Condom manufacturing defect?

Last night my gf and I had sex, and afterwards I noticed that the condom was riddled with holes. They were really small and not visible to the bare eye, and I didn’t feel a difference when using it – I only noticed after I filled the condom with water to check its integrity (like I always do) and water kept pouring out of these holes.

The holes definitely don’t look random. They’re arranged in two completely parallel rows, consistently placed half an inch apart from each other, and these dotted rows go over the full length of the condom, top to bottom. So an accident can be pretty much ruled out.

I was also able to rule out sabotage. I still had the opened wrapper laying around and, after careful inspection, there were no holes in the wrapper. So it’s impossible my gf or someone else poked holes through it. The wrapper was also opened by me, and the condom was only handled by me, so no interruption of the “chain of custody”.

Now, how high are the risks of pregnancy actually? It was my second shot of the night, the previous was like 2 or 3 hours before that. I pulled out right after finishing. Also, my gf’s period is due in 4-5 days, so she should be well outside her fertile window, but you can never be sure I guess. She also washed herself out with water and said she didn’t notice or feel any cum inside her.

Are there any additional precautions we should take?
