False positive or early miscarriage? So confused

I’m so very confused here. I was supposed to have my period last Thursday. On Saturday, I decided to take a test which showed a very faint line! I was so excited and scared as I miscarried at 10 weeks in December. To get more confident, I decided to take another test today, just to see that dark line confirming someone was there...well there is no more line or almost no line. Barely visible quite frankly. Did it happen to anyone? False positive or negative? Hormones dropping meaning it won’t stick? 😢
