I am so happy to have found this thread as I was trying to remain positive and not stress but I also have been having cramps and was fearing the worst. I had 2 eggs implanted on 29/6/11 blood test on 7/7/11 showed pregnancy hormone level at 16 another blood test on 9/7/11 level at 66 and further blood test on 14/7/11 has my level at just under 600. I don't know if these were good/bad level and if the cramping indicated something? But reading through this post has made me feel a lot better thankyou.
