I am on day 23 of a average 26 day cycle. Took a first response and it was a negative. Af is do Friday 8 months of trying and still not pregnant. My fertile window was 25 to the 30. I could only bed in my two most fertile day because hubby works out of town 29,30,31. I am upset and think I am gonna stop trying. My sister is coming into town and guess I am going to try and enjoy our time together.
