My last period was January 7, 20121, I was 10 days late. On February 17, 2021, I tested with 2 lines. I went for an ultrasound and the result was: GS 6mm, no yolk sac, no embryo, there was an early gestational sac inside the uterus and scheduled for February 24 for another ultrasound. Doctor, I'd like to ask if my period is 10 days late, ultrasound shows GS 6mm, no yolk sac and embryo, is that okay?
