TTC while/after extended breastfeeding?

My son will be 2 1/2 next month and I’m ready to wean so we’ve started reading a book called Booby Moon ( highly recommend) , he’s starting to initiate conversations about weaning finally after half a year of trying to get rid of nursing sessions with no luck. I’ve tried everything including cold turkey and it only caused trauma for everyone , my son is VERY attached to nursing but that’s not what I’m really asking about here. So I want to TTC and we kinda have already been not trying not preventing for a year and “baby dancing” at least 1-2 times a week every week for most of our entire relationship. I’ve only had 5 periods since I had him in June of 2021 , and the most recent was in May of this year. I can usually 100% tell when I’m ovulating and then about 14-16 days later I have a period. But because of the highly irregular periods I end up taking like 3-5 pregnancy tests every month on random mornings because I always just expect it to be positive 😂 anyway does anyone have any tips for getting ovulation and periods back while breastfeeding a toddler ? I’m taking beef organ supplements, vitamin D, a good prenatal multi, magnesium, and trying to stay hydrated and eat healthy. I also try to eat a ton but lately I don’t have an appetite.
