Cadence I am also about to start my first IVF cycle and like you already have a 2 yo, a son, and have been TTC #2 for around 18 months.

Can't give much advice on what to expect as I have no idea myself but can be here to support and help. I am on the pill at the moment and due to start taking syneral in a couple of days.

I wish you the very best of luck. Try and relax and feel positive about the fact that you are taking active steps to get closer to your goal!
