First period

So I’ve officially gotten my first period since giving birth and honestly I feel so ripped off since I bleed for 5 weeks and already have my period at 9 weeks 😒 must be because of twins I don’t know lol. Anyway, I’m noticing that it’s a lot heavier then what I’m use to. Going through tampons much faster and even leaking which has barely ever happened in my life. I’ve read the first period after birth can be heavier, I’m just wondering what’s“normal” and will it go back to what I’m use to or am I stuck changing super tampons every couple hours for the rest of my life!?
