🥺 Baby loss prevention

So emotional...😭 If this is what being stabbed 🗡💔in the heart feels like 😣 ..

For the life of me I can’t hold a baby past 4 weeks..I had a wide range of test ..Everything turns up normal from the blood work .I have had test done for my thyroid , Fallopian tubes, uterus cervix the whole nine... Each time I found out I was pregnant it was a day after a missed period . Four days after missed period I start to Miscarry every single time .. dr can’t pin point why this keep taking place . I firmly believe that I have a weak cervix ..

Has any one else Experience the same thing??? 😔😔
