Hey ladies maybe someone can help shed some light on my situation, because it has left me very confused.

I am 5 month TTC now, 1 CP a year ago. AF flow was supposed to come a week ago, my period is never more then a day late. I was feeling alot of strange symptoms that relate to pregnancy like implantation cramps and light bleeding (very light and seemed to be a different colour then a period) It did not feel like my period cramps, and I did not have the symptoms I always have right before and during my period. The cramps were not painful just kind of there. I took a few pregnancy tests across a week and I'm seeing very faint lines. But the line isn't getting darker. Which has left me confused no period, no pre period symptoms, pregnancy test is so faint that I am questioning whether the line is there. I have never experienced any of the symptoms before. So now I am just confused. Anyone have any insight???
