Colostrum at 11 dpo 😳

I am 11 dpo today & noticed colostrum last night. I had been feeling a tingly sensation and my nature reaction was to squeeze my nipples & immediately colostrum started coming out.

I have a 14 year old son which I never breastfed, so Im sure it isnt a result of recent breastfeeding.

Could this be a weird sign of pregnancy?
