Nervous

So on 8/31/17 i had my first miscarriage I couldn’t understand why and blame my self. Then I found out I was pregnant again on January and on 2/7/19 I had a miscarriage for some reason my second loss was more painful and harder to understand. I decided I was done trying. I had unprotected intercourses once and I found out last week I’m pregnant. I feel like i shouldn’t get to excite. I’m so scared I can’t sleep at night and during the day all I think about is if my baby is okay .. but I would appreciate prayer plz thank you ❤️❤️
