Hi there,
Firstly, Yay on starting IVF and goodluck with your cycle!
I think the side effects and severity of them vary from person to person. With the syneral I get headaches, sinus pain and stuffy nose...worse in the beginning, but has seemed to get better as I have gone along.
I'm taking gonal F and find that I feel a little bloated and some occasional tenderness of the ovaries. Generally I find that I am quite tired, a bit snappier/more emotional than usual.
Again, goodluck!
