Hi Aleenta, I too was using Orgalutran/Peregon on my first IVF cycle.
However this was not due to any overstim, as I suffer from sinus the FS gave me this option.

As BW said the needles are a little blunt however very much the same as Trigger.
The only issues I had with them were after the injection I got a little rash.

I started a thread https://www.bellybelly.com.au/forums...cycle-ivf.html
Maybe this can help with any questions as well.

All the best on your journey
