For your first concern, since you are unsure whether it is urine or amniotic fluid leaking, I would not wait until the 20th February appointment as amniotic fluid leaking does need to be checked sooner rather than later, so it is worth calling your gynae or heading to KKH to get it assessed early just to be safe. For the longer term pelvic floor issue, a lot of mums find that working with a women's health physiotherapist after delivery makes a real difference, because they assess you properly and go beyond just the standard Kegel advice to give you a structured recovery plan that addresses your specific situation. It is worth weighing up whether to see a physio versus just doing exercises on your own, since seven years of symptoms suggest your pelvic floor may need more targeted support than self-guided exercises alone. I would raise both concerns with your gynae when you go, so they can refer you to the right specialist after you deliver.
