Implantation Signs?

Follow up post here.

This is my cycle based on 28 days. We are all different and have different cycles so your dates will be different to mine.

Previously suffered 2 recorded chemical pregnancies (in lockdown). Reality is that I have thought I may have been pregnant in the past but the my period arrives within a few days. When I didn’t test for early pregnancy, I did not always know, so ultimately I actually think that I will have had more chemical pregnancies. I am now wondering If this is going to be a positive test and if it is perhaps a good sign with the implantation. Fingers crossed.
