Should I still pump or?

My baby is 13 weeks and she was sleeping right through the night up to about 2 weeks ago. Not sure if it coincides with her 12w leap but now she will sleep 9ish to 4, has a feed then sleeps until 6:30-7ish.

Prior to that she was sleeping like 7:30pm to 6am so at that point I was pumping at about 10pm then again about midnight.

I’m starting to feel really tired trying to stay up late now she’s waking earlier and she’s still sleeping a fairly good stretch for a 3 month old, if I go to bed when she does at 9 will I be setting myself up for problems with supply if I sleep through till 4 with her or should I try and carry on pumping about 12?

Even with evening pumping after she’s in bed I still use a haaka on the morning (I don’t NEED to anymore as I don’t leak now but it was a good way of building a small stash and became habit. I wouldn’t be too fussed about dropping the late night pump in terms of saving milk)
