## Quick answer

- Sex every 2–3 days covers the fertile window without exact timing.
- Extra focus around fertile signs is optional, not essential.
- Legs-up and special positions are myths.
- Look for fertility-friendly lube if you need it.

There’s a lot of pressure around “getting the timing right”. The good news: you don’t need military precision. The NHS’s advice is refreshingly simple.

**Every 2–3 days** The NHS recommendation for sex when trying to conceive

If you have sex every two to three days throughout your cycle, you’ll almost always have sperm waiting during your [Fertile window](https://splash.care/learn/glossary/fertile-window) – no [tracking](https://splash.care/learn/cycle-basics/tracking-101) [stress](https://splash.care/learn/cycle-basics/stress-travel-illness) required. If you like data, you can add a bit of extra focus around your egg-white [discharge](https://splash.care/learn/body-literacy/discharge-decoded) days or a positive LH test.

## Myths you can ditch

**Myth:** You have to lie with your legs up after sex.

**Fact:** There’s no good evidence for this. Sperm that make it into the cervix get there quickly. Cuddle as long as you like, but no gymnastics required.

**Myth:** Certain positions help you conceive.

**Fact:** No position has been shown to improve your chances. Choose whatever feels good.

## A note on lube

Some lubricants may make it harder for sperm to swim. If you need lube while trying, look for one labelled as fertility-friendly, and chat to a pharmacist if you’re unsure.

> **Splash says:** “scheduled sex” can feel like homework. Mix it up – date nights, no-pressure cuddles, and remember sex outside the window counts as connection, not failure.

### When to see a doctor

If sex is painful, difficult, or isn’t possible for you (for example because of a disability or erection problems), talk to a GP – the NHS lists this as a reason to get support when planning a pregnancy.

**Quick quiz:** What does the NHS suggest for the best chance of conceiving?

1. Only on ovulation day
2. Sex every 2–3 days
3. Twice a day all month

Answer: Sex every 2–3 days. Every 2–3 days keeps sperm available across the fertile window without the stress of pinpointing one day.
