From what i was told, just coz you had one, doesnt necesarily mean you will have another....its just chance you may. I had RP with DD#1 (awful, terrible experience....but anyway). PUt me off having children, until that natural urge came along. When pg with DD#2 i researched RP and made sure medical staff knew my history....but no problems here. Infact it was my easiest labour (#2) ....she just popped out.
