3 almost 4 months postpartum

Jennifer

Alright so my babygirl is 3 months almost 4 I breastfed her for 2 1/2 months and 6 weeks after having her I had my birth control put In which is the Paraguard. I know some women won’t have periods while breastfeeding but I would’ve expected one by now. This whole past week I’ve just been cramping and it’s been getting worse and worse I can’t stand it anymore has this happened to anyone please let me know ASAP
