MLR - I want to know why Ive lost my last 4 pregnancies, but carried my first two to term without issue? Why was my last baby alive at 11w, but gone at 12? Why was I told, you'll be fine, your chance of m/c falls to almost nothing now that you've seen the h/b in the last 3 losses?

Im angry, Im bitter, none of the 'fixes' to my apparent problem (a blood clotting disorder) stopped me from m/cing. Why dont they know the answers? I dont know, but I really wish they did. Im pg again and have been told to 'cross my fingers and hope for the best'. Not very scientific is it? Certainly not enough to give me any confidence.
