So I've been using g these since June. I typically get 3-4 days of flashy smiley (high) before solid (peak). This month I had 6 days of flashy and then this morning no smiley at all. Just straight to low. Could I have missed my peak? Did I not ovulate?? I feel a little defeated. I've always had some reassurance with these because it was so clear without squinting to look at strips but now I'm just sad.. anyone??
