After breastfeeding

I stopped breastfeeding my toddler when he was around 2

It’s been 6 months since..

at first my breast were normal after couple months my milks feels like it keeps coming back when my expected period is suppose to come!! But during month they are normal !

It’s uncomfortable

Once my period starts it all returns to normal. I also got very irregular periods so I am expecting my period for sometimes 3 weeks and my breast feel breastfeeding during??

Anybody experience this, can give me advice.
