First Period Postpartum

Anyone gotten their first postpartum period yet? My little one is almost 6 months and I'm EBF so haven't had one yet. However, for the last week I have felt like crap, stomach hurting, cramping. Took a test and o am not pregnant.

All the girls at work are cycling so I am thinking my body is trying or getting ready to try to get back to normal. I know your period can change after baby and was wondering if this anyone else went thru something similar?
