Chele - If you have been on Synarel for a several days now you should start to bleed. Usually you start bleeding around the time they do the first blood test to check that your system has been turned off - that is down regulated. It's a good sign that you are bleeding it means you have bottomed out and are ready to start stimming. It's also probably very good if AF is heavy as I've just been reading that it can really help chances of BFP to have a good lining clear out!
