Who uses the Premom app? Does the chart it produces stay as crap as this? I can’t understand why it was blithering on about CD16 being ovulation day when all the OPKs I’ve imputed suggest that’s very unlikely to be the case! I think I might just use it for the OPK comparisons, ignore the chart and continue to use Fertility Friend! Temping next month might help as well, but I’m unsure, as my sleeping/ waking patterns tend to be inconsistent still…
