For the most part my LH was just elevated all the time. I would get surges during AF, again on time, and again a couple of days after the previous surge. I stopped using them and got pg the first cycle without them, but mced, and then used them the past two cycles after my mc. But I found my body was a much better predictor of o with pain, cm changes and desire to bd. I also charted bbt recently, but before I mced it didn't work either.
