Is there an option to record your period if it's late? I'm 2 days late.... I think.... I was supposed to get my period yesterday... nothing, today nothing.... BUT if they say implantation can occur 12 days after ovulation, that was yesterday? I had slight to mild cramping only on the right side on and off all day yesterday Took a test yesterday and today both said no... should I wait a week and retest if still no period? How do you track late periods???
