TMI picture! Implantation?

​Yesterday afternoon I had a very light pink strip on my toilet paper, and then the best time I had this. Could it be implantation? I was 7DPO yesterday and was taking ovulation best. BD every other day. I've had some slight cramping and backache along with being sick to my stomach here and there. I am trying to not get my hopes up but I am wanting this so bad. Thanks ladies! Baby dust to all :)
