Plan B Timing. San Antonio to New Mexico.

When you’re facing a pregnancy scare, time can feel like it’s moving in slow motion. One of the most common questions we hear from patients at Women’s Reproductive Clinic of New Mexico is: “Is it too late for Plan B?” If you’re in San Antonio and considering emergency contraception, here’s what you need to know about Plan B timing, how the emergency contraception window works, and your options if that window has closed.

Plan B Timing: What It Is and How It Works

Plan B One-Step is a type of emergency contraception (EC), often called “the morning-after pill.” It works by delaying ovulation—the release of an egg from the ovary—so that sperm and egg don’t meet. Plan B contains levonorgestrel, a synthetic hormone similar to what’s found in many birth control pills.

It’s available over the counter, no prescription required. In Texas, where access to abortion is severely limited, many rely on Plan B to prevent pregnancy when other methods fail or weren’t used.

San Antonio to New Mexico: Timing Matters

Plan B works best within 72 hours (3 days) of unprotected sex, but there’s a catch:

• Most effective: Within 24 hours (up to 95% effective)
• Moderately effective: 25–48 hours after sex
• Less effective: 49–72 hours after sex
• Not effective after 72 hours: After three days, Plan B is much less likely to prevent pregnancy.

If you’re searching for “Plan B timing San Antonio,” know that the sooner you take it, the better. Plan B doesn’t work if ovulation has already occurred, and it won’t end a pregnancy if implantation has already begun.

Plan B Timing: Backup Options

If more than 72 hours have passed, Plan B may no longer work—but it’s not your only option:

• Ella (ulipristal acetate): Prescription-only and effective up to 5 days (120 hours) after sex. It’s more effective than Plan B in the later part of the emergency contraception window.
• Copper IUD (Paragard): Can be placed by a provider up to 5 days after unprotected sex and is the most effective EC option (over 99%).
