rip van winkle

My life the last 2 weeks has revolved around sleeping, getting ready to go to sleep and plotting out how long it is till I can go to sleep again.
I don't remember being this exhausted with the other pregnancies, but the level of exhaustion I'm feeling is overwhelming. I've been averaging about 11 hours of sleep a night, with the occasional 1-2 hour nap during the day. And after 11+ hours of sleep I can still hardly get out of bed in the morning. Yesterday I felt dizzy I was so tired so I went to lie down during Pip's nap and I woke up over an hour later in the exact same position - I didn't even budge.

I'm hoping this is a good sign that this egg wants to stick around.
