I have Diastasis of the Syphisis Pubis. DSP or SPD are not indicators of threatened prem labour (I wouldn't have complained if she came earlier though), but it is an indicator for a fast labour, as it makes it easier for your pelvis to open up. If bubs is in the wrong position it can put bub into a position to push the gap further, which is not something you want. If you are likely to have a TPL then just be very aware of how fast you may progress, and maybe ask if you can have more regular appointments to keep an eye on your progress.
