Encouragement?

Finally after being 13 days late, taking pregnancy test and blood work. My blood work came back positive. My dr told me he was concerned about the jump in lvls of hormones and wants me to come back in 3 days. To rule out having an early miscarriage.

Later that night about 3am i started cramping and then bleeding. And it just got worse. Im so hurt, sad, and disappointed. I woke my husband up crying, he converted me. But it just hurts. If by any chance, i could have caused it. I dont know. Should we try again right away or should we wait?

Any advice greatly appreciated.
