Hj1981, thankyou for your words. While i had numerous blood tests during m/c number 3 and then afterwards im not 100% sure about my prog levels! i know i had a series of chrom tests - both husband and me and i also had numerous bloods to rule out autoimmune disorders i couldnt be certain about the prog levels. I have an appointment this month with my ob-gyn and i will be sure to add this to my list of questions. thankyou for your help xx
