How can I cope

I miscarried on November 17th and it didn’t hit me until today when I went to the doctors to see if I was pregnant not meant to start my period for 7 days but he done a test and said it’s negative I finally told my boyfriend I might have lost it because he didn’t know that I had lost it because i didn’t believe it I didn’t want to until today the doctor did a pregnancy test and it came back negative he was crying and a just broke down on him when he hugged is now I can not stop crying my heart is broken😭😭😭😭😭
