Pregnancy test

I'm six months pregnant currently. But, I have people tell me that I might not have really been pregnant to begin with when I lost my Christmas positive last year. So, would y'all consider this a positive? It was took within the time last year. I was four days late on my period. Hence why I took the test, along with other tests. I won't go into details about the day I lost her/him, but I wanna know.. do I have the right to say I have been pregnant 3 tines instead of just two? Or are people right in saying it wasn't really there? I feel like it was. I feel like I should have my baby, but I don't.
