Found out I was pregnant in January lost it February

I was pregnant in January of 2019 and since losing my little angel I haven't been the same. I haven't looked at my fiance the same. I haven't looked at myself the same. I 've been through terrible pain and stress and it's not my first miscarriage but this one hurts the most because it was with someone that I want to spend the rest of my life with. I feel like such a failure. my body failure, I failed me but I'm slowly insteadly getting better. Ever since I lost my baby I wanted to have another one. I have two sons but have always wanted two daughters or just two more children to complete my family that's all and it's been hard because after my second son I had a 3 years ago 9/16/2015. And ever since then I wanted another one so I waited two years and I have been trying ever since he hit 2 years old it will be finally got there and I felt like it was taken away so quickly I couldn't even enjoy it and it hurts so bad. So now I'm lost and I want another baby but it just wish I could feel better too.
