I can only speak for myself. But I might consider postponing my nuptials if I were pregnant and my water broke before the wedding. 
New British wife (and mummy) Emma Lowdon is clearly a heartier soul. As the Mirror reports, her water broke three days before she and her fiance, Sean, were due to tie the knot. Doctors gave her antibiotics and their blessing to proceed with the wedding as scheduled. So the couple stuck with their plan.
Shortly before she walked down the aisle, Lowdon apparently started to go into labor. She managed to fight through the contractions, say her vows and get a kiss from her groom.
Not only that, but she also swung by a reception before heading to the hospital. (I can almost imagine what she must have said: "I know the baby is crowning, but I paid for this @#!&ing caterer. And I am eating some of those crab puffs before I go to the maternity ward!")
The couple's son, Josh, was born the following day (that poor woman, as if the wedding wasn't tiring enough) and was five weeks' premature. But he is healthy. So we wish them congratulations and also offer our sympathies. Sympathies? Yeah. A new baby brings much joy, but I have to think he also makes for the lamest honeymoon ever.
