baby no heart beat

Ya Allah..sedihnya bila doktor kata awak mungkin dah keguguran..betul ke?sbb scan xnampak apa..xde heart beat..scan byk kali..still same result..then another doctor dtg scan..still jugak xnmpak..tapi that doctor ckp mungkin ade miscalculate period..so mungkin masih awal usia kandungan..tue sbb xnmpak..dtg balik 2mggu..so mcm mana ye????
