So I have two <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> that I use and one said I start my period on Jan 29th and the other feb 1st. Well on Jan 29th I thought I started my period and I went to check and it was brown spotting on my underwear I figured my period was just getting ready to come but it’s been 3 days and this is has been it for the last two days when I wipe and on my underwear .... I’m not sure if this is considered implantation bleeding or my period ?
