Help me keep calm!

My cycle has been getting longer (I think because I've been getting healthier). It's gone from 25 to 27 days over the last 8 months. The last four months, I've gotten my peak opk on day 12 like clockwork. Today is day 12, and instead of peak, I got a high reading. Of course, my natural reaction is to panic that I'm not going to peak at all!!! Help me keep calm, please! Is it normal for your cycle to change as you get healthier?
