Phantom pregnancy

So I thought I was pregnant for 3 months and I had all the symptoms and even my belly grew. We thought I was pregnant but turned out to be a phantom pregnancy. My brain said I was pregnant and so did my body but I never was. I feel so empty now and I can’t even look at a baby without tearing up. All I’ve ever wanted is to be a mum and I thought I had that finally but now it’s been taken away. I miss the bump and feel so empty inside. I want it back but it never was there. I’d got to what I thought was my second trimester before I had a period
