Weird question...

Blw
Trying to conceive since August. It would be baby number 2. I'm having bilateral breast pain, as well as areolar swelling. For the past 2 nights I have noticed a teeny amount of clear fluid resembling colostrum seeping out of my nipples on both sides. My last menstrual cycle started on November 7. My next period is estimated to start December 9th. Have I lost my mind or is this an extremely early pregnancy symptom? I haven't breast fed my daughter (now 3) since she was 6 months old & this has never happened before.
