I dont know what to do

I miscarried on the 17th of december after finding out a few days earlier that I was pregnant. My husband and i had been trying for 10 months. I spoke to the doctors and they fed me the line your fine it happens to about 1 out of 4 women. Honestly I still dont understand how it can just happen if there is nothing wrong with me and I'm young and it will happen. I'm scared to try again. Any advise to get through this. And how did the doctors react to you. Wondering what to do next.
