So I'm fairly new to OPKs, but I tested yesterday at 6:30 p.m. after holding it for 3 hours. The result was a stark-white OPK, a.k.a. negative! So... is it safe to assume that I'm NOT going to ovulate in the next day or so?? I would think if ovulation was even remotely on the horizon, the OPK would've shown SOMETHING and not been white, right??
