Well - four weeks after gestation, which is when their first period is missed. I knew I was pregnant at the moment of conception though - many women do - and I did a test well before my period was due, which just confirmed what I already know.

But the fertilised egg doesn't even implant until four weeks after conception, so an abortion at that point is literally a collection of cells - no heartbeat, no fetal pole - just a yolk sac. Sure - if things go well it will end up as a baby, and many women don't know they're pregnant so they can't abort that early, but many, many early pregnancies end in miscarriage which the woman just thinks is her normal period a few days late. It's a very tenuous time.
