Period

this app says I’m 1 day late & my other period app says 3 days late although last month this app was more accurate then my other app. My period is irregular ever since I had sex starting feb . sometimes it’d come on time sometimes it’d be a couple days late. I have no symptoms or feel any sort of way (preg wise) I know when my period is coming I get really annoyed & temperamental as well as emotional I’ve been feeling like that a lot. I’m just pretty sure every girl gets a little nervous when they are late. I go through this almost every other month once I even took 7 preg test because I was almost 2 weeks late . Sometimes I’m 5 days late ugh. Also I have an event coming up in 3 days so I’m hoping this is God looking out 🤞🏼🤞🏼
