15 week loss

Yesterday I lost our 3rd baby, 2nd one in second trimester. I feel like I am just a failure. My heart aches knowing I couldn't save another one. So much was going well. I just seen a strong heartbeat. Perfect in every way. I almost want to not try anymore. The pain is so unbearable. We are having chromosome tests done to see if that may be causing the loses. Still I feel like my body is rejecting these innocent souls.
