well tonight has been the 3rd night on 600iu puregon since the FS upped my dose from 450iu on monday. Not sure if I feel like anything has changed. Occasionally I feel the odd little twinge, but not sure if it is anything. I have been getting some terrible little head aches straight after my injections also which last for about an hour. Fingers crossed for Friday lets hope we get to egg collection next week.
