Bre`ana

I recently started the birth control Mirena on December 19 since then I've been bleeding 😩🤦🏾‍♀️and my supply has dropped 😐. I've noticed that when I pump I don't get as much if any milk. However when my 10week old son nurses he is eating well. I don't understand. Please help me because i don't want to supplement but I don't knoW what to do
