So, I just got a positive opk at 2:50pm today. I am kinda starting to freak out because my SO isn't here and won't be for AT LEAST another 4 hours. I'm worried I'm gonna miss my window! How long do I have before I'm out? Does anyone know an estimated time? I know it's impossible for someone to predict it but I just need some reassurance, if there is any. I'm on cycle day 11 now, last month I got a positive on cycle day 13 but FF said I ovulated on cycle day 15, so I think I have a bit before I really should worry. Also, one more question! I took a Clear Blue digital and got a positive but when I used an Answer opk and it was very faint! So I'm just wondering if a faint line on an opk can still be considered positive or if it's just completely wrong?
