Spermicide?

Had unprotected sex on the day app said it was a 5.5 chance of pregnancy. I can’t take plan b due to a bad reaction, so I only had a spermicide lube which I inserted 12 hours after we had sex, any thoughts?

Update in reply to comments:

No need to be rude “ladies” I’m well aware of how reproduction works, I used the lube afterwards because it was the only thing I had available at that moment and I know it’s to be used before sex, however due to certain circumstances it was the only thing I had and that was the soonest I could’ve use it so I did instead of nothing. I posted in hopes of support and instead received hate. Screw you assholes!
