Cramping bad at 5 months postpartum

Jessica

Little backstory...I've always had regular periods.

I'm 5 months postpartum and exclusively breastfeeding. I had my first period at 6 weeks pp, then had a longer cycle (48 days), then two regular 28 day cycles, and now I'm on cycle day 33. I've been cramping so bad the past few days like my period is fixing to start but it hasnt yet. Is all of this normal while breastfeeding?
