With PGS testing how many cycles of IVF ICSI are needed if 38?

I am 38 years old. I am really trying to work out all the costs and I’ve been offered the 3 ICSI cycle offer with 50% refund if unsuccessful. I am happy I was accepted as there was a medical review for this. However, if I take this offer, I cannot afford to PGS testing and I can barely afford the medication on top. If I do the ICSI multi-cycle which is two cycles, I can just about PGS twice, but I would definitely not be able to save for another cycle. Thanks
