Ladies Help Please

So I’m A Bit Nervous & Confused!! I Have A <a href="">Period Tracker</a> Due To Sometimes Me Forgetting The First Day Of My Menstrual & I Have This One Because I Was Trying To Conceive A Month Back.. I Received My Period For Oct, Nov, & December.. My <a href="">Period Tracker</a> Said I Should’ve Gotten My Period Sunday & This App Said Yesterday.. Not Sure What To Think Or How Long To Wait Before Taking A Test.. 👀🙈

UPDATE: AF Still Not Here, Could I Be Expecting??
