Questioning period length

Jade • 28 / husband is 29. Mommy to Abigail Elizabeth 05/30/17 🎀 Claire Victoria 07/01/20 🎀 Eric James 10/14/21 💙 4/08/19 💍👰🏻
So in January I had a strangely short cycle. The first day was spotting, the next was like a regular period, and the next I spotted again. Then it stopped. Usually I have medium to heavy periods for about three days straight out of a normal five to six day cycle. What do y'all think?
