I'm cd14 and I still haven't had my LH surge according to my stupid OPK sticks. There is the faintest of faint lines, but not even sure if I'm fooling myself with that. My cycle is pretty regular 28-29 days, so don't know if I normally have lower LH surges that can't be picked up by my particular brand, Ovunow. Really frustrating. It's the second month I've used them, and didn't get a really strong line last month either, just a darkish kind of half line. Expected it to get stronger but after that it just disappeared.
Anyone else have this experience?
