Miscarriage experience and so many open questions

I had a miscarriage last saturday at 5 weeks. We got pregnant the first month trying and were so happy, but for some reason I had a bad feeling the whole 1,5 weeks since I found out. I never really got symptoms other than my breasts beeing sore. I wanna get pregnant again asap, but on the other hand I'm sooo scared. They didnt find out why I had the miscarriage and I'm scared that something was wrong with me. What are your girls experiences. I need a little hope at this point😔
