What's inside
Four things worth knowing before you spend another evening Googling "creamy discharge 9 DPO". (DPO means days past ovulation. You're welcome.)
What's actually happening
Implantation lands somewhere between days 6 and 12 after ovulation. Until it does, there's no pregnancy hormone for a test to find, even if everything is going beautifully.
Why symptom-spotting doesn't work
Sore breasts, bloating, cramps, feeling emotional: progesterone causes all of them every month, pregnant or not. Why you'll do it anyway, and how to stop it running the fortnight.
When to test (and when not to)
The earliest a sensitive test can pick anything up, the day results get reliable, and why a negative before day 12 is incomplete information rather than bad news.
The bit that matters most
Alcohol, caffeine, exercise and sex, sorted in a paragraph each. Then the part nobody tells you: how to plan result day so you're not alone with a plastic stick and the silence.
The fortnight, to scale
Days past ovulation. Most of the wait happens before a test can see anything at all.
