TTC after miscarriage

I miscarried this past weekend I was 8 weeks. I passed everything naturally and did not need a d&c. They keep telling me there is nothing I could’ve done to prevent it but I keep thinking and researching that I could’ve. They keep telling me only 1% of women have reoccurring miscarriages but I’m terrified it’s going to happen to me again. I’m taking my prenatal plus from my ob plus 400 mg of folic acid on top of that now for when I start trying again when I stop bleeding. I read that new research found taking baby aspirin when you get a positive result can help in preventing early pregnancy loss. What are some things I can do to prevent this from happening again? Has anytime got their rainbow baby right after their miscarriage.😔
