BFing moms-do your breasts regulate once baby starts sleeping through the night?

My son just turned six months today and this week he finally started sleeping 7-8 hours straight. My breasts are not used to this lol..usually he’s up every 3-4 hours so needless to say my breasts feel like they’re going to explode after 8 hours. I really don’t want to pump in the middle of the night especially now that I can finally get some sleep! So my question is -will my breasts get used to this and not get so full at night? Or will I need to pump to keep supply from tanking or me from getting a clogged duct? Thanks for any advice!
