Then another strong positive the following morning, followed by "weaker" positives that evening and the next morning. By the evening of day 16 it was totally negative. This was my first time using Wondfos instead of the Clearblue monitor so it was interesting to keep testing after the initial positive and see that my surge lasts quite a while.
Anyway, the reason I asked is because I got pregnant this cycle and went in for early betas since my previous pregnancy ended in a miscarriage. I was sort of obsessing over the initial number, which looks a lot better if I ovulated on day 15 or 16 (after my surge started but still showing positive OPKs) than if I ovulated on day 14 (when the surge was first detected). Trying to just calm down and let things play out but part of me wishes I had temped and knew exactly how many dpo I was on the days of my blood draws!
Congrats OP! No need to obsess yet.

Hope this one sticks for you. If not, try temping in conjunction with the Wondfos next time. I've been on both sides of this game and when you've had a loss or two, the extra reassurance is worth it.
