Hello. I Was Recently Pregnant And Lost The Baby At

Hello. I was recently pregnant and lost the baby at 5 months. After the loss I seemed to not accept the fact that my baby was no longer here, in which I continued to feel like I was pregnant and still had a belly. I knew deep down I was no longer pregnant but my mind and body just couldn't accept it. I've never been evaluated for any mental illness and don't know if that may be why I feel the way I do, or is it the grieving process that I still haven't dealt with or accepted. Need help!
