<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period will start yesterday, and clue says it will start today, but nothing at all. I'm kinda stress thinking if I'm pregnant. But all test were negative. I'm thinking of getting next week if I still don't have my period! I don't have the symptoms of pregnancy. I feel nothing. No cramps or anything, and no signs my period is coming. Pls help.
