ttc / menstrual cycle

okay so my bf and i have been i guess you can say ttc for baby#1 for almost two years now and attached is my days app photo that is pretty accurate with Glow, however we've done it a couple times an sadly I received my menstrual February 3 however it was the shortest I ever had honestly! Thursday and Friday I bled, Friday was like medium then light at night and by Saturday it was gone. My cycle is 5days long 3 days heavy so I'm wondering what could be the reason. Has anyone had this occur before? my period was stated to start like next week so it did come like a week early but should I even count it as a period or what do y'all think? Feb3-feb5 was the one I jus had. (No photo attached of that month)
