Quick Scoop: The most useful thing after sex is to lie still and relax for about 10–15 minutes ; there’s little evidence that any special position guarantees pregnancy, but staying on your back briefly is a common, low-risk tip. It’s also best to avoid douching or internal washing, because that can interfere with sperm and raise the risk of irritation or infection.

What helps most

  • Lie down for 10–15 minutes after sex.
  • Keep things calm and comfortable rather than rushing to stand up right away.
  • Avoid douching or inserting anything into the vagina after sex.
  • If you want, you can place a pillow under your hips for a short time, but this is optional and not proven to be necessary.

What matters more than after sex

  • Timing sex around ovulation matters much more than any post-sex routine.
  • Many experts suggest regular sex every other day during the fertile window.
  • No specific sex position is proven to make pregnancy happen faster.

A simple routine

  1. Finish sex.
  2. Lie still for 10–15 minutes.
  3. Avoid douching or vaginal washing.
  4. Go about your day normally.

When to get help

If you’ve been trying for a while without success, the next step is usually to look at ovulation timing, cycle tracking, and possible fertility evaluation rather than changing what you do right after sex.

TL;DR: Rest briefly, don’t douche, and focus more on timing sex near ovulation than on any special after-sex trick.
