BLIGHTED OVUM

My OB declared my pregnancy was BLIGHTED OVUM had a Gestationl Sac without a Yolk, prescribed nia po na raspa daw ako once na duguin nko sa gamot na binigay nia. My QUESTION IS??? -may mga nabasa akong post all over social media, na kusa daw lumabas ung Ges.Sac or inunan, di nila kinailangan ng D&C since wala naman fetus na napunta sa Gestational Sac. May nabasa pko na since day1 na preggy xa,.privte xa nagpacheck, pero nung declared din xa as B.O at need daw raspa, nagpa 2nd opinion xa sa public hosp. Ang sabi sknya doon itry muna na duguin xa at mailabas nia ung sac if wala lumabas saka xa iraspa. Is it true po ba? Anyone here who experienced same scenario?
