My husband and I use condoms as BC. We use them correctly every single time, we are very very cautious and never mess around without. We have used them for YEARS. The singular time we didn’t use one in our over 10 year marriage, I got pregnant (baby is now 3)

I am 3 days late and panic stricken. My heart is pounding. Do ppl seriously get pregnant when using a condom perfectly?! We’re not teenagers that are still guessing at how to use ‘‘em properly. These condoms are brand new, no holes, not expired. Just spiraling right now and it’s late at night with no one awake to talk to. Thanks In advance.
