How often do you get clogged ducts?

Hi I’m 14 weeks pp - almost 15 weeks now - and I regularly get clogged ducts. Sometimes I get them every 10-14 days, but it’s usually at least once a month. They then take anywhere between 16-24 hours to clear. I wanted to see what others are experiencing and if this is normal. It’s so demoralising when it happens, because I then spend all my time thinking about it, how uncomfortable it is, how afraid I am that it’ll develop into mastitis - and then my supply dips after I’ve cleared it :(. I’ve worked so so hard to get my supply to where it is. I am a “just enougher”.

Is it something I’m doing wrong? I take sunflower lecithin daily, I have a breast massager when pumping etc. I use ice/cold compresses and ibuprofen when I’ve got a clogged ducts. Am I missing something?

I would really appreciate anyone sharing: How often do you get clogged ducts and how long do they last for?
