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.
