Milk supply drop

For the past two days, I was thinking my milk supply was dropping. Well today, it definitely has. I just got my mirena iud placed December 12th and it’s the only thing I’ve changed. Can I get my supply up or should I just call to get it removed?

I just bought mother’s milk tea and milkflow drink powder. I’ve been drinking water like a mad woman and eating oatmeal. I’m going to be devastated if I can’t breastfeed anymore. Does anyone have any tips?
