Envious of my sister being pregnant.

Mi
My sister and I both just turned 18 years old and she has a one and a half year old son who I adore. I'm the past I have suffered three miscarriages and I hate that seeing other people getting pregnant makes me so jealous. I know that being this age and pregnant isn't always the easiest thing but since getting pregnant at 15 it's all I've wanted. It's so hard. Just needed to vent and have some people listen. Any prayers for future healthy pregnancies for me is so much appreciated.
