My chart looked pretty promising. Only dip I had was on 9/10 dpo and it was by .1, but today I had a temp dip of .4 on 11/12dpo...im not due for AF for another 4 days. Am I out or should I still have hope? Did anyone else experience this? I just need some experiences. Good or bad. I'm just trying to make it through today.
