TTC. Have been regular for all these months. Last period, 19th May. Tried between the 1st and 2nd. Felt tired the week after. Took bHCG and a progesterone test on the 16th. Results were bHCG =0.34, Progesterone: 12.4. Negative pregnancy test. Doctor asked to come in next day (17th May) for a physical exam. Physical exam showed high progesterone. He suspected pregnancy. That same day, 17th May, in the night, spotted. Was sent in for three tests on the 18th, FSH, E2 and Progesterone. Values are as follows: FSH = 1.5, E2= 93, Progesterone: 13.2. Doctor suspects anembryonic pregnancy (absence of embryo) or a normal pregnancy. Any chance this could be a simple case of late implantation, thus the negative pregnancy tests? Are the other values consistent with normal pregnancy? Doctor has sent me for same tests on Wednesday. Still on embryonic pregnancy or normal pregnancy. What do you'll think. Going crazy here. Thanks
