possibly pregnant after chemical loss

So I had a chemical loss at almost 5 weeks in May. Now my AF is due 6/14. I am experiencing all the same pregnancy symptoms as I did the first time, especially very tender breasts, more that any period has ever given me. I took a 6 days early test today and it was negative and I had some light spotting, I'm hoping that maybe it's just implantation. Can anyone help me with this or has anyone had a similar experience?
