I am so glad that your daughter is doing better! I am a nurse so I know how dangerous blood clots can be. It is amazing how sometimes they can just appear out of nowhere! It sounds like the docs are doing all the right things. Heparin will do the job along with the other meds! We use it a lot and it works! It sounds as if the worst part is over. Catching it and treating it quickly is key.
I will continue to pray for her and your family,
