I’m Scared need some reasurance…..

Well this is my 8th pregnancy and i just turned 20. I’ve had 6 miscarriages and 1 birth n working on my second. My first baby was a little girl I was 13 years old my boyfriend and I decided to take the relationship one step farther well we took it two. 4 months after that first time I found out i was pregnant and at the first ultrasound i found out it was a girl i named her Chevelle. We took her home and her daddy got into the wrong crowd and he started doing illegal drugs around our precious little girl. We had her for about a month and then all of a sudden she stopped breathing one day when i was bathing her I freaked I called Jer he came over and we called 911 and did cpr on her she was so tiny, so perfect, i didn’t understand by the time the ambulance got there she was gone my perfect little princess gone. Now i’m pregnant again after all those miscarriages i’m 15 weeks. I think i’m having a girl again Her name will be chevelle again because i love that name i think its the perfect girls name. Well last friday my collie stepped one my stomache we went to the hospital the baby was fine THANK GOD. But i’m still scared, scared that my child will make it through the pregnancy but then be riped from my arms once again and my dreams or raising my child will vanish like every other time. I love kids and me and my husband have been trying for about 3 years now. With only miscarriages, I have no children. We are currently going through a divorce he started doing drugs and smoking i couldn’t take it, it brought back memories of my little princess i couldn’t bear it anymore i left i found a new guy who i am now having this little one with. He knows about everything but I don’t think he really understands how scared I am even with the pregnancy going good that I still have a fear of losing my child. He keeps asuring me that He’s got good sperm nothing will happen to stop worrying but i can’t help it.
