Extremely fatigued!! 😴😴😴

Amber β€’ Husband and I have been ttc #1. Cant wait to have my own little family. β™‘β™‘
I have been extremely tired this week. It seems like no matter how much sleep i get im still sluggish. I have been in that blah feeling to. I have no clue whats going on. Its my fertile week but idk if that has anything to do with it. Has anyone else had this problem before? If so what was the cause?
