Frexspar: "Today? That would be like you, perverse and inconvenient. The worst possible moment for my ministry. Naturally."
If a woman in fiction is established as near-term pregnant, and there comes an event that would be the worst possible time for her to go into labor, the baby is going to pick that time to be born.
Doesn't matter if it's drama or comedy, doesn't matter when the baby was actually expected to be due, doesn't matter if The End of the World as We Know It is approaching - it's coming now and the cast is going to have to deal with it on top of whatever crisis plagues them. A Delivery Guy will have to go into action quickly here.
Its frequency in fiction aside, this is otherwise actually not as unrealistic as it sounds. The stress caused by extreme or sudden psychological or physical trauma can cause a near-term woman to go into labor, and an earthquake, attack by an army of mooks, apocalypse or the like have been known to be very stressful.
The most common exception, oddly enough, is any episode where the mother is already expecting to go into labor any moment and the drama around the birth itself is the point of the episode.
Compare Imperiled in Pregnancy. Super-Trope of Born in an Elevator. Frequently involves Instant Birth: Just Add Water! and a Screaming Birth. Sister Trope to Away in a Manger, which is a near-term pregnant woman in a Christmas Episode giving birth on or near Christmas.
- In Barefoot Gen, Gen's mother Kimie goes into labor the day the atomic bomb falls on Hiroshima, after watching her husband and two of her children burn to death. Six-year-old Gen is the only one around so he has to help. (All the doctors and nurses were too busy trying to help the bomb victims.) Sadly, baby Tomoko dies shortly afterwards as well, because Kimie (like many people in her community) was starving due to the high cost of food, and because of that, her milk dried up. Gen worked to get powdered milk for Tomoko, but by the time he managed to save enough money and buy some, it was too late; Tomoko starved to death.

- In Safe Havens, rain starts coming down in freezing weather, leading to iced roads. So of course Ming and Jenny go into labor at the same time. Somewhat downplayed, as Ming had always planned to give birth at home anyway, but still. To be fair, Dave shouldn't have tempted fate like that.
Dave: I don't want to think about being iced in with two pregnant women on their due date.Jenny: Ug. This party dip makes my stomach hurt...every ten minutes...
- In Chapter One of Sonic the Hedgehog fanfic A Rose And A Thorn 2: Eclipse, after a perfect day, watching a perfect sunset, a nervous Shadow is trying to give Amy his carefully planned wedding proposal when she goes into labour on the beach.

- Not really a "maternity" crisis, since in this case the birth is an egg hatching, but seen in the third book of the Temeraire series. Of all the times for a baby dragon to hatch, it would have to be just as the cast is on the run through enemy territory with almost no food, right?

The pregnant cop gets to the hospital without much hassle but the baby's father is in charge of the search so she forbids anyone to call him so he will not be distracted.
- Lampshaded by John Sheppard in Stargate Atlantis when the city goes into quarantine and he is trapped with a heavily pregnant Teyla.

- Bella and the Bulldogs: It's bad enough that the Bulldogs' playoff game is moved to the same day as Pepper's mom's baby shower, which Bella said she'd attend.

Cue Pepper's mom going into labor...with her husband fishing at the lake...and only Bella, a hyperventilating Pepper, and a fainting Sophie there to help her. And the only one not in labor with even a driving permit is Bella...meaning a 15-year-old girl who's had one ("technically one and a half") driving lesson is driving a woman in labor to the hospital...and trying to finally get to the playoff game.
- Sisters. Second-youngest sister Georgie, nine months pregnant with the baby she's carrying for youngest sister Frankie, gets into a car accident and promptly goes into labor. It's not clear if she would have gone into labor regardless or if the accident triggered it.

Just as she finally makes it back to the hospital stop, she collapses and has to be carried the last few feet by her co-worker Luka.
- Firefly probably tops every example in this category by having a woman deliver a child in a bordello while the local mob boss and his hired thugs are shooting the place up. On the plus side, the Delivery Guy is Simon, who's a doctor (albeit not an OB/GYN) and therefore knows what he's doing.

However, Lindesfarne doesn't realize she's in labor until after the terrorists are arrested and carted off, and after the adrenaline wears off. (In case you're wondering how she missed such a big clue, the terrorists were trying to drown her.) To make matters worse, she's a good distance from civilization, being a councilor at a summer camp, and the only one qualified to deliver babies is busy with other patients from the terrorist attack. Luckily, with the help of Carl and Leona, she safely gives birth to her daughter Turvy.

- Hey Arnold!:
- Arnold finds in his father's diary that when Miles and one friend were taking his mother Stella to the village and suddenly get caught in a volcano eruption, the poor woman went into labor. LOUDLY. Luckly they found shelter in an ancient ruins.
- A variant: Arnold and his friends are stuck in a stalled subway car with a few other passengers, including a Blind Black Guy whose seeing-eye dog suddenly seems very sick. It turns out to be a case where Your Tomcat Is Pregnant (why a trained seeing-eye dog wasn't spayed is anyone's guess).
- Martha Speaks: It is revealed in "The Jakey Express" that Mariella went into labour while pregnant with Jake on a snowy day and the car had broken down. They weren't prepared either, as she wasn't expected to give birth until two weeks later.
