Weird period

So I lost my virginity not too long ago and have had sex pretty regularly since. Not too long after I got my period a day early which wasn’t too weird since I have an irregular period but It’s weird because I immediately knew something was a bit off. I usually have a medium to heavy flow w noticeable clots and this period my blood seems more thin if that makes sense I’ve seen small clots and it’s bright red but I got it really heavy one day like it filled a whole pad in under 3 hours and then the next I barley bled and then immediately after I thought I was done but I bleed through on my pants just. I’m just confused and a bit scared.
