Feeling bad!

Last June I was late 2 months and got a positive pregnancy test but then at the doctor office got a negative, they told me it was probably a chemical pregnancy, a year later I’m pregnant with my baby, but for that year I just told myself my period was late it didn’t happen could of been a false positive even though that was the only time in my life my period my period was off, when I went to the ob she told me that is still a miscarriage even though I wasn’t sure in my mind and she wrote it down and I was in shock and still am I can’t believe I could of lost a baby and then I feel weird for being in denial that it happen, I feel so confused?
