So this is the forth time I went back for blood and the nurse called to tell me that levels have dropped and I'll eventually expel the embryo. She said to stop taking the progesterone and in not so many words basically give up and expect for myself to start bleeding it out. I don't want to give up. It's been over two years and tons of fertility treatments . Has anybody ever experienced this and then have a positive turn around? I'm looking for hope.
