Pumping

So I just pumped while my husband gave our son a bottle of my pumped milk before bed. I only got 2 oz on each side... WTF? Is my supply dwindling?!! Is it the pump? Normally I can get at least 4 from my achiever boob...

My LO is 14 weeks

It’s evening and I do pump less at night... 😭😭 HELP!
