Ok, so last month my period came about a week early. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> said that I'm supposed to be on today. Could I be pregnant or could I just be going back to my original period time? I haven't really been having my period symptoms like I usually would. Normally I cramp really bad, I have bad headaches, my boobs are sore but this month just sore boobs, slight headache and hardly no cramps. Please someone respond and tell me something lol
