Completely understand how your feeling and as PP there is alot you can choose to stress about in IUI's and IVF but at the end of the day all the stress and worry is actually counterproductive. I was petrified before my first IVF, scared of the needles, scared of how EPU would work etc. In the end yes the first time you give your self a needle is hard but it DOES get easier. As for EPU, I eventually found out my clinic does it under general, so you dont feel a thing ... It ended up being a lot easier than I expected. I am heading into our second IVF in November and this time round have no anxiety at all...
