Hey Leez,
How exciting that you have started! I am due to start on the 26th and the wait is torture!! I was actually just researching excercise as I haven't been doing any for the last few months. I think if you stick to low intensity like walking,etc you should be fine. Also don't let your heart rate get too high and not hot saunas. I have started using my in door rowing machine and will alternate between that and just taking a slow walk. Excercise keeps you positive and gets the blood going so I am keen on keeping up something simple

I have also cut my caffeine intake right down and increased my water. I'm really nervous for the weight gain during the actual cycle.
My cycle looks like this (who knows if it will actually stay that way!):
Day2/3: Scan and start stims
Day 8: Scan
Day 10: Scan
Day 12: Scan
Day14/15: Egg retrieval
Transfer either day 3 or day 5 after retrieval
Please keep us updated!!
Lots of love xx
