Still trying with no success

Julia
My other half and I got pregnant almost two years ago and were devastated when we lost the baby almost three months in. We stopped trying for a while after the miscarriage but within the last 6 months I started trying again but we haven't had any luck idk if it's him or me or maybe we aren't cut to be parents. I've watched all my great friends get pregnant with no problem and I feel like a complete failure because I can't get pregnant. I know it sounds really bad but I want a baby so badly because when my other half and I watch my adorable 1 year old nephew and three month old niece we just become happier and more at peace. We want nothing more then to add to our family and it's so devastating to constantly be upset everytime my period rolls around.
