Boobs hurt, randomly started leaking, pregnant?

Hi,

I’m 10 days away from my period, (ive no clue how to calculate dpo).

I have a 1.5 year old already. I am no longer breastfeeding. We stopped at 7 months. Woke up with real tender boobs and they started leaking. Is this an early sign of pregnancy?

I know it’s too early to test, want to see what you all experienced after first kid.

Thanks in advance!
