When you started dropping sessions did you ever notice that your pumping output decreased at other sessions (after it leveled off)?

Long story:

I WOH and breastfed + pump. I have 1800+ ounces in the deep freezer and can finally stop pumping at work (2x), my morning pump, as well as drop doing his dinner time feed (which is his most distracted one and the one that drives me the most crazy). That's great, but now I've been having to go through and figure out how to eliminate all of this. I'm finally done pumping at work and wanted to start tackling my dinner time feed. At the same time, I noticed that my morning pump, where I usually get 8 ozs, has dropped to 5 ozs and now 2 ozs. I think he might be eating a little more in the morning, but I can't imagine he's upped his intake by 6 ozs?? Nothing has changed, EXCEPT, it's the week before my period and sometimes I am a little lighter with my pumping.

Any thoughts? Should I just go ahead and drop the morning session? My husband (in all his pumping expertise) said I might as well since my body seems to be indicating it.
