Oh no?

So I haven’t had my period for two years. I lost it right after getting onto a steady schedule for my period. I just got it and have had it for 13 days. Is this normal for it to go so long for not having it in a long time? I’m 16 btw. The period is also not a hard core flow as in I need a pad some days but rarely need to put a tampon in. It’s more clots and blood in slimey discharge. Sorry if this is tmi
