I hate my period now more than ever, ever since it came back after i had my baby its all out of whack. When it used to come on time every single month, now sometimes its early, and sometimes its late. Like now. Im 4 days late ugh. And breastfeeding exclusively didnt stop it from coming back 3 months pp 🙄
