Mine too, but it tends to be level-ish, then dip, then rise, then level out but higher. I don't use OPKs. Apart from my anomaly of a December cycle, which I can't explain, I find temping really nice for confirming ovulation. What's different this cycle is I've honestly felt like I've been ovulating constantly since Saturday morning, which isn't possible, so just intrigued by what's going on.
