I think you should test twice a day, my surges are really short, so when i start getting somewhat darker lines i start testing twice a day, and if i didnt do that, i wiuld miss the surge. So test early in the day and once late afternoon or early evening aswell :-)

I would say not yet probably tomorrow or next day. I take mines every day at the same exact time to get a pattern going of it getting darker. It works well I think. 😁 baby dust to you!  Oh and heck when it dobut just baby dance every other day !!!
