Implantation ?

I ovulated the 12-17th and my boyfriend and I had sex a few times during that time and didn’t try to prevent from getting pregnant. I started spotting on the 29th and I’ve been having a light pinkish spotting for a couple days. Could this be implantation bleeding ? Fingers crossed that it is. My boyfriend and I had a miscarriage at the end of May beginning of June and we really want to have a baby
