According to glow I was supposed to get my period yesterday but still no period. My other <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> says I'm supposed to get it today but still no period. I took a test on Sunday the 28th of September but I drank earlier on the day. It came out negative. Could this have been a false negative pregnancy test ?! I don't want to test today because I feel like I should wait one more day to avoid any false negatives or positives. What do you guys think?! Thank you
