I guess is normal

According to <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> I’m 8 days late. He cum inside on August 31. Took a test last week on Friday and negative. But I checked on mydays app and is state that next week is my period day. I only have bloating and sore boobs and mood swings, sleepy in the day. I guess is all normal. But wish could be pregnant. If the arreola is not darken then it’s not a sign of early pregnancy?
