I'm 4+4 today, so very close to you!
I found out a week ago and almost immediately felt extremely tired. Napping every day, which isn't like me at all. My sleepiness is at its worst at lunch time, so grateful I WFH!
I can't believe things happen this quickly! Although I am extremely anxious about letting myself get too excited this early on. It's my first pregnancy but feels too good to be true - terrified about things not working out but trying to remember it's out of my control
