Question

Charlie • Army wife, mother of 3 (2 👧🏻 & 1 👦🏻)

I have a question I'm hoping someone can answer here for me. I got a positive opk on the 4th of this month. I am now 2 days late with bfns, but I'm getting almost positive opks. I know you can get a surge before your period, but how long does it last because I have had almost positive opks for like 6 days now. I have even tried a different brand of opks to make sure I didnt have a bad batch. I'm completely confused right now.
