Post breastfeeding hormonal imbalance?

I stopped breast feeding early spring and my periods have been weird since then. They’re super heavy and I spot for 5 day’s before my period. I just feel like my hormones are so out of whack and not sure how to get them back in balance. Anyone have any ideas or went through something like this?

Ps- I’ve had an ultrasound and they said everything looks good 🤷🏻‍♀️
