So for anyone who has the Nuva ring as birth control you know you put the ring in for 3 weeks then take it out for the 4th week (the period week) then repeat. So today is supposed to mark my period week and I just took my ring out. But <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period isn't coming for another 10 days and I'm a little confused because I'm new to this birth control and the last time I was sceduled to have my period after I took the ring out, my period came immediately, and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>'s prediction was correct. This time all I see is discharge.
