A chemical 5 months after a miscarriage? What's wrong with me?

I am at the ideal weight, I eat right, don't smoke or drink, I do everything that I am suppose to.....

Please someone tell me what to do next? I am heart broken.

My miscarriage back in Feb went on 7 weeks but the baby never grew past 4weeks and 5 days and now this.

Bottom test is from this morning.
