Ouch! What was that?
A few years ago, a friend of ours was on her daily commute whilst about six-months pregnant. As she walked from the station car park to her train platform, she saw her train approaching and broke into a brisk jog in order to catch it (in heels, with her heavy laptop in tow). Almost immediately she felt a searing pain in the front of her pelvis. Resuming to a walking pace she felt the pain subside a little, but her pelvis felt different and the pain continued throughout the following days.
