Cycle changed from 28 days to 25?

I had a baby in March of 2020, fully stopped breast feeding in February of this year. My period seemed to be regular then The past 3 months my cycle has been 25 days long. They’re cut short by a couple of days of spotting before my period fully kicks in. I want to start ttc soon and I’m panicking about my cycle being like this. Anyone have any experience with this or can give any advice? Feeling like it’s going to make it 10x harder to conceive than it already is 😩
