Good that they were able to get the contractions stop! Just take it easy, and no more sex!
TT, a lot of women have said that they feel like they need to go to the toilet during labor because of the baby's head decending, and putting pressure on the colon. If you are full term that is just fine, and not a problem, you want that head to drop, but as WM is just 30 weeks, she didn't want to take the chance that it was the baby decending.
