At my doctor's office on Thursday, I had my first post positive beta ultrasound. Tim wasn't able to be with me because of his trip. He'll be there next time, though! We saw the implanted embryo. Dr. Young thought he should be able to see the fetal pole (central nervous system -- I think) but wasn't able to find it. We also saw the other embryo, it had implanted, but not grown very much. That one will most likely just be reabsorbed back into the uterine lining. Dr. Young was pretty calm about no fetal pole, just said that all pregnancies were different, and we'd be able to know for sure in 2 weeks. In 2 weeks, if we see the fetal pole and the embryo has grown the way it should, then we're back on track. If it hasn't, then the pregnancy won't be viable.
Of course, I'm worried. But -- our take on this is we don't really have any control over whether it will turn out to be viable or not. It helped that I talked to a friend who had twins via IVF and at her first ultrasound, one fetal pole was visible and the other was not. The second one showed up 2 weeks later and now he's a rambunctious 4 year old. Plus, if the fetus isn't developing like it should, it's better to know now.
So please just keep thinking about us and praying for us. I'll let you know the outcome of ultrasound #2 in 2 weeks!
