Breastfeeding journey

I’m having some mixed feeling about my breastfeeding journey and could use some advice/opinions.

I reached my breastfeeding goal of 7 weeks (this is when I returned to work). I get an iud placed and my supply dropped drastically within the week. I wasn’t having success with pumping and the stress of trying to increase my supply while going back to work seemed like a lot so I decided to stop my journey. I’ve been pumping for comfort for about a week. I was fine with this decision at first but now I’m regretting it. I’m considering trying to get my supply back up.

I’m struggling because it is so much work but I also know that it’s so beneficial. How did you know that your breastfeeding journey was over?
