Severe pelvic pain when bending?

Over the past couple of weeks, when I bend over a little I have severe pain shoot through the front of what feels like my pelvis. It doesn’t feel like round ligament pain, but more like pressure/burning/shooting pain at once. If I lay down or sit down it stops. It’s instant. However it makes walking very difficult at times too and causes a lot of pain. My doctor keeps saying it’s round ligament pain but it’s getting to the point where I’m in tears and it’s getting worse. Anyone else experience this?
