Need help on exercising routine!!!

Hi lovely ladies, I am not sure if this question already been asked on the forum before but I wanted to understand if running hampers in your chances of conceiving. I usually run around 5km 4 times a week and was scared if doing it in my TWW will cause issues in implantation. I am 33 years old TTC#1 since the last 4 months and looking at my temp drop this morning I guess this month I am out too 😐 I don’t want to make any mistakes next cycles as I am anxious to conceive soon considering my age. Please advise 🤞
