So this is my first cycle being monitored by the fertility clinic. My AF started the 19th of this month my baseline labs were estradiol = 66 pg/ml , progesterone .6 ng/ml, LH 3.32 Miu/ml, endo lining 3.33 mm . Started taking 5mg of Letrozole CD 3-7. Today on CD 10 my left ovary had 2 follicles 12.57 and 9.18. The right had 8.21. Labs estradiol = 76 of/ml, progesterone .6 ng/ml, LH 7.33 Miu/ml, and endo lining 6.87. 
No idea what most of this means. I go back Wednesday for more blood work and another ultrasound. Anybody know if this is good bad normal not normal. Lol I'll ask on Wednesday but it would be nice for some insite.
