Miscarriage 4 weeks ago

I had a miscarriage exactly 4 weeks ago on christmas day. I got my first period after my miscarriage on the 22nd, and its now the 26th and its like stopping. Ive always had my period for 7 days, so its a little weird to me. Just wanting to know if its normal for it to end early the first time around? Its my first miscarriage and everything im going through is all still new to me. So any information will be so helpful! thank you !!
