Updating daily w pics (scope and opk) Secondary infertility - starting a support thread :)

Hi guys :) it's Natalie - I'm 29 years old.. if your coming over from my tweaking thread you prob know I hate FRER and I am experiencing a year of secondary infertility for no apparent reason. I am not skinny or fit by any means but my bmi falls in normal range and I have 3 children ( DD: 7yo, DS: 30 months, DS: 12 months) w the same man and can't get pregnant w number 4 to save my life. 30-32 day regular cycles with regular ovulation day 17-19 every cycle.. Normal thyroid, estrogen, progesterone, fsh tests. His sperm passed w flying colors.. Only 1 chemical in October 2015 cycle and nothing before or since since ttc after my youngest son. I am so frustrated! I am taking Soy isoflavones out of sheer desperation this cycle. And trying Preseed .. Going to the dr on April 1 and am going to try clomid next cycle.
