6 dpo very fatigue

So for the past two days and today I have been sooo exhausted. Almost like when you have been out in the sun all day and you are just worn out. I never get that fatigue during the day, and I also have gotten a lil more constipated(tmi) lol 😂 anybody know if these could be early signs? I know it is very early and don't plan on testing until the day of my AF is due. Blahh😴😴
