Thanks all for the comments, I know the blood test is the best. I am currently out of town on work. I left the anastrozole at home. When I get back I have appt with my GP for routine Blood pressure check up (started meds not to long ago). I will ask him for a lab order he usually has no issues with this , its also done right in the office (labcorp is onsite). So by the time I get that done it will be about 8 days with out the anastrozole. So would it be safe to say if the estradiol comes back low or even all the way up to my normal level. that the symptoms were attributed to low e2 (also if they get better or disappear in the meantime). Dr. Saya I can also forward these to your office when they are done to get attached to my chart. Also I would assume if I come back high then yes I need to start taking the anastrozole again. Just so nervous, I know Im in the best hands with Dr. Saya though. I am liking the HCG, I have noticed not a size increase yet but the testicles have firmed up.
