So... Its been 2 weeks since I delivered baby girl and I am still bleeding bright red and passing blood clots. On top of that I keep getting cold and weak. I take a nap and I feel a little better then it repeats. It hurts my pelvis to lift my legs onto the couch and also when I stand after sitting for awhile. I really do not want to go to the ER but I am wondering if this could be concerning. I don't want things to get "too bad"
