Disappearing BFP and then BFN?

Knottie1445631780

hi everyone, I’m new here but not new to IVF. I have had one failed cycle, one cancelled cycle, one chemical pregnancy, and I’m currently in the 2ww hell. I use donor eggs due to my premature ovarian failure. I transferred a frozen 5 day hatching blast on Oct 29.

So, I felt a TON of twinges and pricks in my uterus the day following my transfer. Slowly, I added dry mouth and low back pain to the mix. Low back pain was a symptom in my chemical cycle that wasn’t present in my mock cycles or my failed cycle so I believe it to be a pregnancy symptom. 

On the evening of 4dp5dt, I got a faint BFP on a FRER. It came right up, was definitely pink, and noticeable without squinting or altering. Then, I looked at it again about an hour later and the line was gone. ?? Coincidentally, I had lost the cap to the test (how does that even happen) so I assumed maybe it dried differently?

So, I took another test on the morning of 5dp and got a stark white negative. Even took the test apart to be certain it was negative. 

Has anyone had either or both of these happen? Am I having another chemical? I’m too scared to test again!! 

Sorry for the novel - thanks in advance!!

Hey @Knottie1445631780 - I'm sorry but I don't think anyone here will be able to tell if that's a true positive or not. One thing I would say is that 4 days past transfer is generally too early for a HPT - it's better to wait until ~9 days or ideally for your Beta. I've heard of all combinations of cramps/spotting/pain that has led to both bfps and bfns - so I'm afraid none of those are conclusive either. I'm sorry - there's no way around it - we all just have to wait it out Wishing you the best result
