It might, maybe your body just needs to adjust back to it

@marissamorris, well it was working just fine . But I don't pump consistently do you think that has anything to do with it ?

If you're exclusively breastfeeding sometimes women don't respond well to pumping. You may produce a lot but not able to pump it out. Also different pumps work for different women. I respond well to electric pumps but my friend doesn't, she can only use a manual pump to get enough
