Ok so a couple days ago I took a clear blue test because I had light brown discharge but never actually started my period. That was 11dpo. And it looked positive. Took a cheapie walmart one later that day and got the most faint line. Here we are 13 dpo and today I woke up and had some light pink spotting and took another pregnancy test but this time took a FRER and I'm sure I still see a line but to me I feel at 13 dpo I should have a darker line right?? I'm suppose to start my period and today I have had light pink discharge only when I wipe off and on today and so I'm just worried!!! Anyone have similar stories, bleeding, or had a light test like this at 13 dpo and still carried full term? I'll post my clearblue first one, walmart cheapie, and first response.
