It may just be too early. Wait the 2 weeks as the doctor recommened and by then, it should certainly be detectable.
Thanks nandi.
Is it proper to take progesterone inj. in order to prevent miscarriage?
no i dont think a injection would do much in this case, i think that it might jsut be too early to see something for sure and depending on the shape of your uterus it could have just been missed, i would wait till the Dr check you again and go from there
did he talk to you about progesterone injections? are your levels off?
I took progesterone inj with my 4th pregnancy and still miscarried. However with my pregnancy now (5th) i started taking progesterone supplements orally starting at 3 days after ovulation and so far have not have any issues, I am now at 13 weeks. Low progesterone can cause a miscarriage, however there are typically other problems causing the low progesterone but the low progesterone is the most noticeable issue. If the baby isn't developing the way it should progesterone inj/suppl won't help with the outcome.
Good luck, and just be patient, I had the same issue too. At my 6 week ultrasound there was a small gestational sac but it was about 1 1/2 weeks off from where it should be. I came back in 2 weeks and everything was measuring where it should be. It is amazing how 2 weeks during pregnancy can make such a huge difference.
