Life isn't fair

My partner and I have been TTC for almost a year. We were over the moon albeit terrified to find out we were expecting. I'm often irregular and tested on the first day of AF due. Nothing. I thought it was just another month of no success. I tried not to keep testing as I didn't want to get my hopes up like i had done in previpus months when AF didnt show. I finally tested and got my BFP. Less than a week after, I didn't feel right and started bleeding heavily. I went to the hospital and they confirmed I was having a miscarriage. A week later my midwife called for an appointment too as they didnt communicate with her. I only knew about you for a week but it hurts. To make it worse my best friend had the same dates of her last period and is pregnant. Why is life so unfair? 💔
