Why Me Though??

I went to the doc for a checkup took a blood test and found out I was 4 wks pregnant.... This was my first pregnancy, as I know of, and soon as I got happy and told everyone there it go light bleeding turned to heavy bleeding and I was starting my period. Researched it and found out I had a chemical, when something can go wrong, IT DOES!! My dude so happy since it would've been his first too. I still haven't told him or my or his family and our baby been gone almost a month. I'm so hysterical I don't know what to do!!!! I just want to go into hiding!!!!
