We werent planning it, but why let the miscarriages discourage me from celebrating this baby now? What happens, is gonna happen. You just have to trust in God.
I know how you feel. Im 19 & last year I lost 2 babies as well. I dont know what went wrong either, but almost a year later, im pregnant again & hoping for the best.
You're 18, you shouldn't be trying to conceive right now. Get on birth control, and focus on school, your education, and building yourself.
Could be a number of things. Your doctor should be able to run tests to figure out what's wrong.
