This is my second pregnancy and my doctor and I are both very confused about my ultrasounds. Going by my last period, I should be 8 1/2 weeks pregnant. I do believe I ovulated late, though. Last period was Oct. 22. I got my BFP on Nov. 18th. I went for my first appointment on Dec. 15th and the doctor saw only a sac that measured 6 weeks pregnant and a yolk sac. Six days later (yesterday) I go back. At first he tells me it is still just a sac and perhaps a blighted ovum until the nurse said “look to the top right, there is movement”. So he moves his transvaginal ultrasound wand all kinds of directions and eventually finds a little bean stuck to the side of my uterus with a visible flicker inside. The machine picked up on the heart beat very faintly, but it wasn’t enough to confirm the pregnancy. In only six days the embryo grew a bit and now has a heart beat that is only visibly seen. Doctor looked perplexed and said “there’s something in there and there is a flicker” but he doesn’t want me to get excited. He’s running some bloods on me and and I’m going back in a week for an ultrasound. I’m wondering if maybe I’m just super early or is there something wrong with this embryo? Why is it so hard to find?! Anyone have a similar experience?
