Extreme Fatigue.....

It has been 1 week since my miscarriage and I have been pushing myself trying to get back to “normal” but it still feels like an emotional roller coaster.. But extreme fatigue has hit HARD!!! I literally feel like I can’t do another thing or I’m going to collapse... I slept most of the day and had to take a nap by 7:30 that evening... Is this normal??
