@KittyDeFleur - i was in the same situation as yourself. The most important thing is to find the best IVF centres that give you the most chance as you are forking out a lot of money, time and going through a lot. Also, the less IVF cycles you go through, the less disruption at work. Once you have a list of these (in melbourne it was Melb IVF and Monash IVF), filter it by clinics that are closest to your work or home. Once you find the most convenient it's not too disruptive. You will need a couple of hours off for the initial consultation and to pick up the drugs and also for Egg Transfer. For this i just said i had a drs appointment or called in sick that day. If you can work from home this would be ideal, last minute oh i need to work from home. You will need 2 days off for Egg Pick Up and recovery. Just say you have surgery booked. If you need more than one IVF cycle just tell your boss they found something that requires a few surgeries. Don't worry they won't ask anymore. As for all the blood tests and OB appointments, try to pick an OB that is close to your work. If your clinic and OB are close to work you can do these over lunch time and the blood tests and ultrasounds are all done very early. So you could go in at 6am if you really want (so just make sure your clinic allows this. The top ones should as they know most of us are working women).
Goodluck! Once you are in it you will find your routine but i was also worried before i started. It ended up not too bad. Hope this helps! xx
