The morning after: what to do

The "morning after" isn't always dramatic — often there's nothing that needs doing, and this guide is just reassurance. But sometimes there are practical, time-sensitive things worth handling, and knowing what they are in advance means you can act calmly rather than panicking. This is the checklist: what's urgent, what can wait, and what's just about looking after yourself.

First: is anything time-sensitive?

Two things are genuinely time-sensitive, so deal with these first if they apply.

Emergency contraception — if pregnancy is a possibility (a condom failed, none was used, or another method may have failed) and you don't want to be pregnant, emergency contraception works best the sooner it's taken. Some forms are most effective within 24 hours, though options exist up to 3–5 days depending on the type. The copper IUD, fitted within 5 days, is the most effective option and also becomes ongoing contraception. Don't wait to "see" — if it's relevant, sooner is better. The emergency contraception guide has the full details on options and timing.

PEP for HIV — if there's any chance of HIV exposure (unprotected sex with someone whose status you don't know, a condom failure with a higher-risk partner), post-exposure prophylaxis (PEP) can prevent HIV, but it must be started within 72 hours, and the sooner the better. This means going to an emergency department, sexual health clinic, or urgent care and asking for PEP — it's not a next-week conversation. If in doubt about whether it applies, a sexual health clinic or emergency service can advise quickly. The PrEP & PEP guide covers this.

STI testing: note the date, test later

It's natural to want to get tested immediately for peace of mind, but testing the morning after is usually too early to be meaningful. STIs have "window periods" — the time between exposure and when a test can detect them — and testing before the window has passed can give a false negative. Different infections have different windows, ranging from a couple of weeks to several months for full confidence.

The practical approach: note the date of the encounter, and plan to get a full STI screen a few weeks later (a sexual health clinic can advise on exact timing for different infections, and may test earlier for some). If you develop any symptoms in the meantime — unusual discharge, pain, sores, rash — get seen sooner, as symptoms warrant testing regardless of the window. The when-to-get-tested guide covers the timelines in detail.

Physical self-care

A few small things help physically:

• Peeing after sex helps flush bacteria from the urethra and reduces the risk of a urinary tract infection (UTI), which is common after sex, particularly for people with vulvas. If you develop burning when peeing, needing to pee frequently, or lower abdominal discomfort over the next day or two, that may be a UTI — treatable, but worth seeing a doctor or pharmacist about.
• Gentle cleaning is fine, but avoid harsh soaps or douching internally — the body is self-cleaning, and aggressive washing can cause irritation or infection.
• Watch for anything unusual over the following days — significant pain, unusual discharge, sores, or other symptoms warrant a check-up. Most of the time there's nothing, but knowing what to watch for means you'll notice if there is.

Emotional self-care

However you feel the morning after is allowed — good, indifferent, unexpectedly low, or complicated. The emotional aftermath guide covers this in depth, but the short version: post-sex feelings vary enormously, an unexpected low mood ("post-coital dysphoria") is a normal physiological comedown and not a verdict on anything, and feelings of attachment after sex are partly chemistry. None of it means you did something wrong.

If what you're feeling is regret about a choice you made, that's worth sitting with gently — it can be useful information about what you want going forward, without being something to punish yourself over. And if part of what you're feeling is that something happened that you didn't fully consent to or want, that's different and more serious — the consent guide and the Urgent page have support, and none of it would be your fault.

The reassurance

Most mornings after need none of this — no emergency contraception, no PEP, no concern. The value of knowing the checklist is that if something is relevant, you can handle it calmly and in time, rather than discovering the time-sensitive things too late. Prepared and calm beats anxious and scrambling. And if nothing needs doing, you can simply get on with your day.
