Beta drop

My beta in Monday was 29. I got word today that it was 27 on Wednesday. Morning sickness set in last night (Thursday). Doctor said to expect a miscarriage this weekend. We are praying for a miracle. Doctor said there isn't any hope but said I could continue my meds and test again on Monday if I want. I know a miracle can defy every impossibility. Would you pray that God spares this little one's life?
