I recently had a my first miscarriage Monday, still bleeding, 
My question is, is it normal to be relatively swollen? Like abdominal (very bloated) And legs? Very little but some.
Also, prior to this pregnancy I've had sciatic nerve issues pain and numbness from it. For the past 2 days I have been in bed literally all day (coping/healing) and I'm SUPER NOT USED TO THAT! I'm used to being on my feet long periods at a time. I woke up today and decided to get out the house for the first time and my legs have a tingling numbness to them like the beginning stages of them going to sleep not painful or anything. It also helps when I walk around. COULD THIS BE FROM BEING LAID UP FOR SO LONG? Or SOMETHING PINCHING MY NERVE?
