I had my hysterectomy in oct 2010 I had my right ovary and tubes taken, but left ovary was left. then August 16 2013 i had to have emergency surgery they had to remove my left ovary. Dr put me on Vivelle 0.05 did not help, i end up putting 2 on at once for a week and it helped me alot even with sleeping.. So I went back to Dr. and she put me on Minivelle 0.1 and last night was the first time using it, and it has not helped me, I woke up with a headache, i still have it now, I have had the heat flashes all day on and off... So whats the difference between the two?? What do I need to do?? Thank you
