Anyone Else?

Pa

So my boobs have been leaking for months but only like little drips at a time and mainly when I lay on them. But for the past 2 days my left boob has been just straight up leaking non-stop. It was each boob would drip and leave little spots on my shirt if I wasn’t wearing a bra but now it’s just my left one and it is leaving my whole boob completely wet. Should I be concerned that only one is doing this? Why has it started to leak so much? I’m 36 weeks with my first. Have an appointment tomorrow and plan on asking then but just wanted to know if anyone else was having this happen.
