Hi Sonya,
I have had no side effects with moods, boobs, or anything else for that matter with puregon 300IU daily except the swollen, very sore ovaries and I still have only had 14 measured at scan yesterday. I think it must vary a lot with each person because, the way I'm feeling with this many and the way Bec felt with 60 is pretty different!!! I was quite nervous too until I had my scan and I hope that will put your mind at rest too. Good luck!!! I cant wait to hear how you go.
