Kkh after misscarriage control

Hi ! I just went for my D&C procedure at KKH around 1 weeks ago and scheduled to go back to see the specialist on 15 May , however had a call earlier and the specialist ask me to come back on 24 April instead. I’ve been so scared! Not sure what kind of test they did with the specimen of the baby? 🙏🏻🙏🏻😭😭anyone have same experience? Please help!
