Hi ladies! AF is not supposed to come until 4/6, I took a test today (10dpo)and thought I saw a SUPER vvvvvvfl but was probably an evap (see photo below) I am having cramps like AF usually provides before she decides to show up uninvited...should i keep testing over the next few days or just wait for AF to show up?
