Not pregnant but it feels so real!

I had an confirmed miscarriage back in may. I have a almost 7 month old baby and 2 year old. I have tried to move on from losing one but i cant shake some feeling im having. I have noticed over the last 3 weeks i feel little flutters, super hunger, tired, and ect. All the feels i got when i was expecting my girls. I took a pregnancy test for it to come negative. Im so confused i feel like im having a phantom pregnancy because of my loss. Yet, it feels so real! Help!
