Your story sounds so familiar to me. I was also in denial and put off seeing an FS for 2 years - worst thing is now I wish I hadn't as I didn't realise how long the IVF journey would take.
I just had my first failed IVF cycle and I had 3 day embryo transfer too. I'm new to this site and I've noticed everyone talking about blastocyst and I'm unsure of what it means. FS told me that we'd leave it a little longer before triggering next time but there's never been any discussion about the 3/5 days...I forgot to bring this up at my appt yesterday!
So now that I've seen your thread saying you are concerned about it...it's got me wondering...?
In regards to the needles etc everything was fairly easy and pain free. The worst thing was miss dumb ass - I was so forgetful! (it's good to have something to blame it on!)
I hope everything goes well for you...sometimes it's the unknown that is the hardest part. BB is great for finding people that understand, it's great know that you're not alone
