Okay, so this is the BEST <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period App</a> I ever decided to download and use, its even more accurate then the P.D.(period Diary) it would tell me that I was certain days late. (fast forward) Now That I deleted THAT app and started using this <a href="https://play.google.com/store/apps/details?id=com.glow.android">GLOW APP</a> I have found it MORE accurate then the Period Diary, Last Month my cycle came on time according to the calendar and the SAME THING HAPPENED TODAY, I just really LOVE Using this app for my cycle BEST App EVER, YES!!!!!!! 🤗
