Extreme tiredness....

Well the last few days have been the most tiring I think so far in this whole process. On Monday I woke up feeling like I hadn't slept at all. I had headaches for most of the day and have felt a bit zoned out. I called in sick on Tuesday and slept till 11am (after getting up at 7.00am for my morning Buserelin injection). Just an overwhelming sense of exhaustion. I guess I'm a little nervous now as we are getting close to all the good/big stuff... We have our ultrasound tomorrow which will let us know how I'm responding to the medication. Possible egg collection on the 19th but it can change at any time.
