I Am 5 Weeks & 4 Days Pregnant. I Went

I am 5 weeks & 4 days pregnant. I went to the ER w/ light cramping on Wednesday. The on call OBGYN said I had blood in the sac w/ the baby. He scheduled me to come do another blood screening for my HCG levels. On Wednesday my level was 6,052 and today (Friday), my level is 8160. I don't have any vaginal bleeding but do you think this will result in miscarriage?
