The latter part of the lack is what contains the progesterone,which is what most people struggle with. Try and keep a small account of what/how you were feeling on each day see if a pattern emerged on which tablets you were on. No need to get too obsessive though,I got hubby to photocopy a blown up monthly planner and just jotted down a few things,just a couple of words will do. Femoston does seem to be better tolerated by most but not all. It's very much trial and error I'm afraid. Also look at other aspects of your life,exercise,diet,doing things for you etc.
Good luck .
