Is it normal to take an OPK and not even get a faint line until your peak? I've seen posts where people post pictures from days leading up to their surge and they had faint lines that got darker. I never got that. I have only ever got a dark line one time that gradually got darker threw out the day. But the day before and the day after no lines. I even took a CB test and it got the smiley face. I havent got any lines and I should start ovulating tomorrow but kinda scared to think that I'm not ovulating because the opks only showing that one day.
