Failed abortion, concern over implant.

Patient: I had a medical abortion last year. Whilst having this done I had the implant inserted. One month after the abortion I discovered I was still pregnant, although the foetus I was carrying had no heartbeat. The abortion was not affective. About 2 weeks after discovering this I miscarried. Since then I haven’t been feeling myself. I have been concerned about the effects that the implant may have had on my body whilst I was still pregant. Do I have any reason to be concerned?
