Can you get pregnant if you use a condom?

Possibly but: Not likely unless it breaks or leaks. It is effective but not 100%.

Yes: If you use condoms perfectly every single time you have sex, they're 98% effective at preventing pregnancy. But people aren't perfect, so in real life condoms are about 85% effective — that means about 15 out of 100 people who use condoms as their only birth control method will get pregnant each year. https://www.plannedparenthood.org/learn/birth-control/condom/how-effective-are-condoms

Absolutely, yes!: Condoms leak, come off, or are not used properly, all of which can facilitate unintended pregnancy. Some males "want to get a few strokes in " before applying the condom.(pre-ejaculate fluid contains sperm.) always "back up" a condom with a vaginal spermicide such as the vcf film, to improve the conraceptive "outcomes".(smile).
