The NHS's own pregnancy guidance says to avoid contact sports with a risk of being hit and activities with a real risk of falling, which rules out the rougher parts of a normal kickabout but not the game itself. The honest answer to is it safe to play football pregnant is to adapt rather than stop, with three specific swaps that keep the five minutes going.
I watched my partner go from full-pelt one-v-one to standing still and just passing, and worried for a moment that the real game had gone, until I realised our boy hadn't noticed the difference at all.

Is it safe to play football pregnant?
The NHS advises against contact sports with a risk of being hit and against activities carrying a real risk of falling. Read the NHS guidance on exercise in pregnancy.
This guidance is about a pregnant person's own sporting participation in general - it doesn't name football specifically, but the contact and falling risks it warns about are the rougher, unmodified parts of the game, not the gentle, adapted version this page recommends.
Backyard football while expecting
None of this means giving the habit up. It means three straightforward swaps for the rougher parts of the usual game.
No direct shots at close range. Swap to passing only.
No sudden twisting turns. Swap to stationary passing games.
No diving or lunging for the ball. Let it roll to a stop instead.
What actually changes on the day
Standing further apart, taking the standing or passing role rather than the chasing one, and stopping well before feeling tired rather than pushing through - these are the practical, everyday shifts that make the swaps above work without turning the game into a chore.

The habit still counts
A slower, gentler five minutes together still counts. A child rarely notices the adaptation the way a worried parent assumes they will - what matters to them is that someone is still out there passing with them.
Quick answers
The NHS advises against contact sports with a risk of being hit and against activities with a real risk of falling, so a gentler, adapted version of the usual game is the safer approach rather than stopping altogether.
Direct shots at close range, sudden twisting turns, and diving or lunging for the ball are the three things worth cutting out first.
Usually far less than a worried parent expects - the habit itself, not its intensity, is what most young children actually value.
Keep going
Three places to go next, depending on what you're working on. Once the baby has arrived, playing football with your child after the birth takes the same gentle approach back into the game.
