I REALLY NEED HELP! CAN SOMEONE HELP ITS AN EMERGENCY :(?

MY FRIEND IS 12 WEEKS PREGNANT AND SHES BLEEDING HEAVILY AND IN ALOT OF PAIN. NO ONE IN HER FAMILY KNOWS SHE IS PREGNANT BECAUSE SHE IS ONLY 13 YRS OLD. SHE THINKS SHE IS HAVING A MISCARRIAGE WHICH WE BOTH HOPE SHE IS NOT. BUT IF IT COMES TO HER HAVING A MISCARRIAGE. WHAT DO WE EXPECTED. DOES SHE HAVE TO PUSH THE BABY OUT? IS THE BABY BIG OR DOES IT JUST COME OUT LIKE A LITTLE BLOOD CLOT?? I REALLY NEED HELP. I DONT KNW WHAT TO DO TO HELP HER. SHE DOESNT WANT HER FAMILY TO KNOW BUT IM NOT SURE WHAT TO DO WITH HER!!
