Implantation bleeding?

I had a chemical 11 days ago and on the last day of my bleeding I had a high reading on a ovulation test I bedded that day as I thought the bleeding stop but it returned.. anyways I have bedded everyday since and just now an hour after me and SO bedded I went to the loo and saw this... when I lost my little one 4 years ago I found out because me and my SO bedded and I had this also so could it be implantation bleeding i’m really hoping🌈🌈🌈
