Hello, hoping someone can help as I’m feeling very worried. This is my third FET transfer (none successful so far) I had a strong by positive test on frer and beta HCG of around 450 on around 11dp5dt. I then did a frer a few days later and it was a die stealer so I was feeling confident. My second beta was 7 days after the first and the clinic told me they wanted to see a 10x increase in HCG over the 8 days but that mine had only increased 8x. I now need to get an early scan at 6+3 as they have said it may be non viable.
Has anyone had experience of levels rising less than 10x over a 7 days period and still had success? By my maths, 8x over 7 days is a doubling rate of every 3 days instead of 2 which seems to be in the normal range. Any help would be great greatfully received as I’m not getting much from my clinic 😭😭
