Fam guild after birth

Ima • Classical American Mom

Looking for good sources for preventing naturally after birth. My husband and I are okay with the chance... But would like to wait till lo is a year to ttc.

When does bbt start working. I exclusively breast feed ever 2 hours (all night 😴 and day) and still got my first period 6.5 weeks post partum lo is 3 months I'm about to finish my second cycle.
