I recently had a chemical pregnancy...I am now paranoid about how hard I am working out and if that had something to do with it. I know they are common and it is unlikely working out caused it, but it does not make it any easier. I have been doing HIIT/spinning workouts for 3 months now and before then ran distance. My heart rate can get as high as 190 while working out. Could this affect implantation in anyway? I am currently 2 DPO. Thank you in advance.
