I’m 5.5 months pp. I also get cramps sometimes... occasionally related to baby latching on, and sometimes it just comes and goes. Also no period. I just wait for it to pass...
Perhaps it’s your womb that is shrinking back to its original size. You should go see a PD if you think sth is amiss :)
I'm 8 months postpartum and my period comes every 2-3 months. I still get cramps sometimes without period.
Best to consult your gynaecologist...
Period may not come so soon if bf.
Better to see a gynae
