I'm sorry to hear about your previous miscarriages. I'm 8.5 weeks along too. I've been nervous about miscarrying but my doctor said it is out of our control for now. Try meditation, light exercise, or some other activity you enjoy to help you relax. Good luck!
I had a miscarriage it was terrible I cried for weeks and I got pregnant again but couldn't enjoy because I was so worried but I pray pray pray and pray. Try not to worry about anything unless there is something to worry about. I know it's hard but God is good Congratulations and enjoy your pregnancy
