Worrying

Chastidy
I'm 9wks and it's so hard for me not to worry I've had two missed miscarriages (meaning there was no cramping or bleeding,go to regular Dr. Apt at 18wks and there is no fetal heartbeat so I have to deliver a dead baby) plus a regular miscarriage and an ectopic pregnancy. I try to think positive and not stress but it's not easy. Has anyone else gone through this before
