So let me set this up. We were not actively TTC this month..but we would be excited if we got pregnant. We were planning to start next month. Well my period is a week late (first time other than when I was pregnant with my son). I tested and got some responses that there may be a faint line. I OV late in my cycles so not surprising if there would be a VVFL. I always have issues seeing any faint lines. Honestly- I don't really see anything but I plan to continue testing BUT Saturday we have a outdoor concert with friends. I want to have fun and possibly have a drink with my husband. What would you do? Of course if I got a positive test there would be no question.
