What Does This Ultrasound Report Indicate?

Question: Hello , I am XXXXXXX ( 27 yr old , housewife) having One baby boy 1 yr old born on 21 may 2016. After that i got pregnant again but miscarried unfortunately due to Long journey done. So aborted the kid on 5 march 2017.
( that time it was 3.5 mnth pregnancy)
Now it has paassed 4 mnths of that miscarried. Last mnth i checked through Prega news & it was confirmed again pregnancy there . Then i thought to abort it again in fear of unhealthy pregnancy but when my Gyny. Told ki nothing to worry to go ahead , i agreed so went for SONOGRAPHY yesterday. ( sonography report attached).
In sonography report "EMPTY SAC" is showing with uterus size 70x55 mm & oval shape gestation SAC 28x16 mm in cavity , decidual reaction all around.
1) my last MC was 30 april 2017.
2) my husband was outside so probable concieve date is 27 may. ( very near to my next MC date ).
3) I m Rh negative mother , took injection/Shot prescribed during abortion last time. ( 5 march 2017).
Kindly suggest what does it mean. ??
1) Will it be a healthy pregnancy throughout??
2) Empty Sac without foetus ?? Does it mean if i ll cont. With this , my kid may not be healthy or will born with minor abnormalities like handicapt type , weak bone formation etc.
Plz suggest suitably. Else suggest for abort if there any chance of not getting healthy pregnancy or baby born with complication.
Kindly reply suitably.
