Is it true?

Read an article today about “cold uterus” and the importance of keeping your feet warm. I’m almost 6 dpo and had no clue about it, and my feet are always cold, day and night. After I read it I put socks on and wrapped my feet in a heating pad, however I think I might be too late since I probably should’ve started that right after I ovulated. Whoever did this, how exactly did you do it? Did you keep heating pad on your stomach, or feet or did you take hot baths? I need some insight
