Why??...why does this keep happening?

After finding out I was pregnant the day after I had to put my dog to sleep... after telling family and friends I was expecting on Christmas..after telling my two small children I was giving them a little brother/sister... after seeing my husband get so excited during our ultrasound and being told everything looks great.. today I miscarried..for the 3rd time. At 7 weeks my hormone levels went down to 900.. I never felt sick.. or connected to this pregnancy..but I wanted it so bad.. my heart is so broken. Broken for my kids..my family...my husband.. myself. I dont know if I want to even try again.. what if it keeps happening? I'm so lost and hurt... I dont know where to go from here... seeing the little baby disappear on my glow app when I put that I was no longer pregnant felt like the biggest punch in the stomach...
