Nighttime with a 10 week old

I’ve noticed my baby starting to sleep a little more than usual (she was sleeping 3 hours at a time) she’s now upped this to 4/5hours… however I’ve noticed by the time she wakes up im leaking ready to feed her, usually my bra or the bedding is soaked… does anyone recommend what to do? Will this last long, or is it just where we’re going longer intervals than before? During the day she’s feeding on and off loads, with minimal naps unless they’re contact naps so I don’t notice it during the day!!
