Having IVF with ISCI soon. Still debating PGS?

Hey everyone! I had some questions and looking for some advice/shared stories. My husband and I have to do IVF w/ISCI. Did you do PGS? We have never been pregnant. We are mid 20s and doing the genetic screening on us to see if we are any carriers of diseases. Just waiting on results. Our next decision before our cycle deadline is to do or not do PGS. I'm anxious about some of the injections before retrieval.. do they hurt? We are willing to do anything to become parents. According to our Dr, naturally we have less than 1% chance of it ever happening on its own. Thank you all for any advice/input!
