Exhaustion!

Katie • Our first is so fun - let`s have another!
Month 4 TTC, and I've been so tired all week.  (AF due July 1-3, depending on which app you consult.)  I ditched caffeine a few months back, so I don't think it's withdrawal...  But is it?  Or is my baby making equipment stealing my energy?  
​I nearly fell asleep at work early this week.  I've never done that!
