20 weeks, leaking, & boobs hurt

Ashley • 31 yrs old, RN. Wife of 10 years, mommy to our sweet 9 yr old & baby girl born 9-11-16!
I'm 20 weeks and last night and today my boobs have been so achy and painful!  Even woke me up last night hurting.  Noticed I started leaking this afternoon- just a few drops.  Is the pain and achiness normal, too??  It's like a stabbing, achey pain.  Just want to be sure I don't need to call my dr.  No hard lumps or anything, no fever I'm aware of.  Thanks for the advice.
