I did 2 embryos Transfer on May 5th (did the 24 chromosome check, on day 4, very good quality embryos, one of the embryos was already blastocyst on day 4 morning and the other was one stage before blastocyst which is pretty normal). 8 days after my transfer, my HCG was only 10. Then 48 hrs later it was only 17, then 72 hrs later today (i.e 13 days post transfer) my HCG is only 27. The doctor said that my pregnancy is so weak that if I stopped the meds I will most probably get my period and miscarry. The doctor said that if next test (after 2 days) the result is still that low and not doubling, i will stop the meds. I am on estradiol 2 mg 4 times a day, progesterone injections once a day, Crinone progesterone suppositories twice a day and Estrodiol patches that release approx. 100 mg in 24hrs. I've been crying since I knew the result. Please help me with your advice and experience!!!!
