Signs of a prolapse?

Anyone here been diagnosed with a prolapse? My ob/guns keep ignoring my symptoms and I feel like I have a bulge when I stand up. I am only 30, but I’ve had 4 babies in the last 5 years and I feel like my pelvic floor is shot! The last 3 babies have been larger babies (9 lb+). I have been doing Kegels, but have still been feeling a deep pressure. I am not done having children so would definitely love to strengthen it a bit more before going through another pregnancy. Thanks!

Get a second opinion. Two women I know personally have a deep pressure type feeling and ended up one had polyps and the other stage 4 cancer everywhere.
