Is it my period?????

My second ever period was on the 27th of Feb and it was a regular amount of blood and on the 3rd of April (since its my first periods they arn't regular yet) I got a tinny bit of blood on my undies like not even a 5c coin size. It went on for another day and then it just faded out... Was it my period? I heard periods don't stay the same heaviness (you know what i mean) in the first year... that my be happening because my first was REALLY heavy, second regular, this one blahhhh. What is happening? Advice?
