Phantom kicks after pregnancy loss

It's been a week and a few days since I gave birth to my angel at 23 weeks. Losing her has really taken a toll on my body and mind, more than I could have ever imagined. But one of the hardest things is that I feel as if I can still feel her moving around inside me. Now that I know what kicks and baby movements feel like, every phantom movement lifts me up, then I remember she's gone. I'm not feeling her squirming around. It's very depressing. Has anyone else experienced this? How long does it last?
