Help trying to figure it out

Sorry Y’all! I don’t know much about all of this but I’ve been very very irregular for years. Sometimes not getting a period for almost the whole year, one month I’ll have a few drops and that’s it. Well I’ve been losing weight and exercising and since November I got my first full period in years! Here comes December January and February.. AF showed up every time. Well, per not just glow but other trackers I’m late 2 days in one app and 1 day in glow.. here is my data if anyone can help me out. Last period was the week of Valentine’s Day. Per Glow I was supposed to get AF yesterday! I don’t feel anything out of the norm except for feeling tired. (Not normal for me to yawn at work but had a crazy week so maybe just tired) any help would be appreciated

Also, any cycle buddies!? 😊 sounds weird saying that as it’s been sooooo long. Haha!
