My cycles are getting really long since my stillbirth in January--now around 40 days. But I'm now on CD31 and no positive OPKs yet! They started getting darker for a while (never got dark enough, though), then started getting lighter and lighter. Can someone take a look at my chart and help me figure out what's going on this month? (I had a stillbirth at 34 weeks in January and a CP in early September.)
