Thank you ladies.
So, I got migraines on 30/150mg gederal, but not on 20/150mg gederal. Conclusion had to be it was too much estrogen. I had other symptoms like extreme breast pain too.... All gone on the lower dose.
However, my original symptoms are now coming back, so I think I need more estrogen. Therefore the only option I see is to try 39mg again but with a different progesterone from the other side of the ladder, in the hope that that progesterone allows me to tolerate the 30mg estrogen. Does that seem right???
tomorrow I pick up my microgynon.
