Thinking I'm out this month:(

Rachel
According to glow my fertile window was 6-23 to 6-30 with my estimated ovulation day on 6-26
On 6-26 through about a week a had cramping on and off and white discharge starting at the beginning of this week I still have the discharge as well as heavy tender body 
I am also cramping again AF due 7-12 and I keep getting negative tests 
I got pretty excited when I started cramping a few days after ovulation cause I thought maybe it was implantation but I think I am wrong :/ 
I have been using preseed lube and taking pre natals seems impossible to conceive baby #2
