You should only cover her up if she is in an area where there is a lot of activity. If she has privacy then just leave her be. If you do need to cover her then wait until she starts hanging around the bottom or if she has been this way for 30+ days. Also, to verify that she is carrying you may be able to feel them. When you cover her be careful not to interrupt her light cycle or watering. Based on your picture she appears to be dehydrated so make sure you have a dripper for her.
Just my thoughts
