I can hear the worry in your question—that uncertainty is genuinely stressful, and it's good you're thinking this through carefully.

Here's what matters: **condoms are highly effective at preventing HIV transmission when used correctly.** The risk of HIV transmission through vaginal sex with a condom is substantially lower than without one—we're talking about a reduction of roughly 95% or more when the condom stays intact and in place throughout.

That said, a few realistic points: condoms aren't 100% perfect (no prevention method is), and the specific risk depends on factors like whether there were any breaks, the partner's viral status if they're living with HIV, and other variables you can't always know in the moment.

**Here's what I'd recommend:** If you're concerned, getting tested is the most concrete step you can take. HIV testing is straightforward, confidential, and widely available. If exposure happened recently (within 72 hours), post-exposure prophylaxis (PEP) is an option worth discussing with a healthcare provider or urgent care clinic—it's time-sensitive but effective.

Testing at baseline, then again at 6 weeks and 3 months, gives you clear answers and peace of mind.

You did use protection, which was the right call. Most people in your situation who test are negative. Reach out to a clinic, sexual health hotline, or your doctor to discuss testing options—they handle these conversations constantly and without judgment.
