Aiyoh don't worry too much first, quite a few mummies in my prenatal class actually went through the same thing and their gynae also told them the same, for many it does improve significantly after delivery, especially once the baby's weight is no longer pressing down. My friend went to see a pelvic floor physiotherapist at KK Women's and Children's Hospital after her birth and she said it was really a game changer, the physio gave her targeted exercises beyond just the usual Kegel and she felt much better within a few months. Someone in my mum WhatsApp group mentioned that one in two women actually experience some degree of prolapse during pregnancy, so you're really not alone, just that nobody talks about it lah, very hush hush topic. The trade-off is between waiting to see if it resolves on its own post-delivery versus being proactive with pelvic floor rehab early, most mummies who started physio early said recovery was smoother, though a couple felt mild symptoms lingered longer than expected, especially those who had longer labours. Either way, do bring it up again specifically with your gynae or ask for a referral to a pelvic floor specialist after birth so they can properly assess your specific situation!
