It\'s a no go...

So the nurse just called and my beta number on Tuesday was 1566.  Today it droped to 1200.  We didnt even discuss the Progesterone level.  She told me we would stop the progesterone injections and if I didnt start bleeding by next week to give them a call.  I dont know where to go from here.  My husband and I have talked about it and we are going to use protection for a couple of months just to let my body get back to normal.  Hopefully I will still be ovulating on my own.  I dont know what causes low progesterone.  I tried calling the RE's office back but they were closed.  I will call them tomorrow or I will just google it.  I hope every body gets there BFP this month.  Baby dust to all.
