Pre-implantation genetic screening

Hi everyone. First time posting here... sometimes it feels like there is nobody to talk to about fertility issues so thought I would try this. My husband and I are about to go through PGS with Sims Dublin. We first went through ICSI two years ago and that produced 5 embryos which we froze and which we thought at the time was a good amount but they resulted in 3 failed transfers, one failing to thaw and one pregnancy that resulted in miscarriage at nine weeks. I am 34 and the doctor was surprised that we have been somewhat unlucky so far so has suggested PGS. It is quite expensive but we are hoping it will give us some answers and let us know whether to continue with transfers. I am in two minds about it because even if results are normal it’s the mental and emotional journey you go through with the medication, injections, waiting for results etc that I don’t know if I’m ready for but conscious that I’m not getting any younger. Has anyone had a similar experience or has tried PGS and was it worth it? Thanks.
