So, on the last day of my period I have a tiny bit of blood like once a day and I add that in as part of my period.. should I? Because the following month my <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> says that I’m supposed to start the day before I always start my period. So, I was supposed to start yesterday the 11th but started today the 12th according to my app. Should I take that last day off my app so it’ll be more accurate on Glow? I just don’t want to mess my ovulation predictor up because this month we’re going to try for the first time. Also, if I always start the day after Glow says I’m going to start does that mean I’m irregular and shouldn’t try? Thanks.
