Miscarriage.

Shawna • I love my 19 month old but... it`s time to TTC #2
I got a BFP last week. Had terrible cramping Sunday went to ER and they told me that the baby had no heart beat and I should miscarrying any day... Well today the bleeding started and I'm in extreme pain and emotional. Does anyone have any experience with this or know how long it takes for it to be over? My husband and I are heartbroken and I just want it to be over already.
