I tested positive 2 1/2 weeks ago and had my first Dr. Appointment today. My cycles are not regular so it was an guesstimate as to the first day of my last regular cycle was, May 1-5 was my guess. That particular cycle was 2-3 weeks late, however. My Dr did a vaginal ultrasound today, he said I only measured at 6 to 6.5 weeks, but spotted no embryo and said my yolk was slightly swollen, although he did say it was perfectly round and otherwise healthy looking. My question is,can this be normal or am I doomed to miscarry?
