Failed 1st FET.. Negative BETA at 12dp5dt

Not really sure why I'm posting this as there's nothing anyone can do or say to change things but I found out today I had a negative BETA on a first FET at 12dp5dt. Fortunately or unfortunately I wasn't expecting much as had negative HPTs since I started testing at 9dp5dt. Still a huge heartache and disappointment and my heart is with those going through the same. Truly wish everyone the very best of luck and baby dust. It was a 'perfect' hatching 5AA blast and my uterine lining was optimum at 10mm so who knows what went wrong. We have 5 more frozen blasts 2x5ABs 2x4BBs and 1x3AB so I know we are extremely lucky to have more shots. My clinic doesn't offer PGS testing and I'm so scared they are all duds but know we have to hope for the best. Sending love and best wishes to all ❤️
