The same thing happen to me. Im sooo sorry for your lost. I had a miscarriage in March, by baby’s heartbeat was not present at 10 weeks. It was heart wrenching. My due date was October 8 and that day was really hard for me. I might be pregnant again i dont know yet and i am also scared that this might happen again. Congradulations on your pregnancy. Best of luck to you and your baby.
