Is this condom alright?

well, I never remember to go out and get condoms anytime before , and i never want to run out the exact mminute before i have , so today i just had 2 kind of oversized condoms, and i knew they were both too big to prevent pregnancy by just wearing one, so i put one on the other and hoped it worked. Does anyone think that would work? it was the right length, but the width was just a little bit bigger, so i put both on at the same time. Does anyone think that was effective?
