Shianne • TTC Baby #1 Praying for my bundle of Joy.
Ladies is it normal to have so many "CLOSE" positives after the OBVIOUS positives posted in first pic. I ovulated on cd12. (2nd pic was taken on cd15,16&17)  I usually ovulate on cd 16 or 17. But last month af came early so I am suspecting that is why I ovulated early. Help please
