Update. I'm not out yet.
My appointment on Wednesday showed my progesterone level even lower, at 5.9. Low, and falling = not great news. However, my HcG levels are doubling like they should be. An ultrasound showed a gestational sac and yolk sac and a little hint of a fetal pole, but no fetus that could be measured. So, when I was 5w5d, I was measuring closer to 5w3d. Then again I have no idea when I ovulated so....that's not necessarily bad news. But not exactly reassuring to hear that they can't actually see a baby in there....
Wednesday morning they started me on progesterone suppositories, and told me to come back on Friday for another beta, and next week for another ultrasound. Basically we're going to keep me artificially high on progesterone, and give the baby some time to develop / play catch up. If the HcG stops rising, or the ultrasound doesn't show a weeks worth of development, I will stop the supplements and just miscarry naturally.
My husband is sooooo optimistic about this. He's hearing the reassuring words that they are saying ("it's not that bad", "we don't know anything is definitely wrong", "I supplemented both of my pregnancies too", etc), and I'm the one over here reading between the lines. I hate feeling so dreadful, and I'm usually so cheerful, I just...I just don't feel like it's going to stick around. And that's a little heartbreaking.
I do have a question, if anyone knows the answer. If my HcG levels are rising exactly on schedule, but the progesterone is lagging behind....does that just mean that I suck at making progesterone? That the pregnancy is still "developing", but that my body just might not be able to hold onto it? Or does low progesterone mean that the pregnancy itself is most likely doomed / was not viable from the start. I keep hearing conflicting things from various experts. Is there any consensus out there?
