Is false negative possible 12 days home urine test after blastocyst .

[YellowRuffle]

Pls does anyone experience increase in body temperature from day 9, my tailbone pain me down to my left leg / hips sometimes, with tummy discomfort after embryo transfer? Can a home urine test also give false Negative 12 days after blastocyst embryo transfer?

Also I prone to OHSS so my clinic went for short protocol. Any one with these similar experiences to share pls?

False negatives are possible but at 12dp a 5 day transfer it’s probably unlikely to be an unreliable result, sadly. My clinic give us a hpt to use on day 11 and if it’s negative on day 11 it’s game over. I just don’t want you to get your hopes up sorry xx
