Pumping and maintaining supply

J1

So I used to pump 7 to 8 times a day. My baby is currently 11 weeks old. Since last week I have started pumping five times a day, like every 4 to 5 hours. The last pumping session of the night is around 11:30 PM. Post that I pump at 7 AM or nine or 10. If I keep pumping this way, will my supply drop? In a day I usually pump around 27-28 ounces in these 5 sessions.

In the very first morning session I pump anything between 6 to 10 ounces.

Oh yes and I exclusively pump, only breastfeed the baby at night when he wakes up till morning 6-8am.
