Hello ladies, I am currently PUPO with my 4th transfer but am not so hopeful as I already had 3 unsuccessful ones and so want to plan my next steps. I still have 6 blasts left but they are of poor quality (all have C’s in them) and they were produced from frozen eggs, meaning they have been frozen and thawed twice, which might explain why I had 3 (and maybe soon 4) unsuccessful tries with them. So I am thinking of having a new egg retrieval with PGS testing to increase my chances. My main concern (other than the financial and emotional toll of going through all this again) is about the impact this will have on my health. Because of my specific issue (thin lining), I have to have stims (Gonal F) before each transfer. Over the years (counting failed cycles etc.), I have taken stims 10 times. I am now worried going for extra cycles could be bad for me on the long run (cancer? Other issues?). Does anyone know anything about this? My dr says there is no research really into this but that stims don’t seem to be dangerous...not very reassuring! TIA for any advice!
