10 dpo and producing colostrum?

Weird question. I’ve never had this happen before and it’s my first time for it.

Backstory- I have a daughter who’s 5 years old. I exclusively breastfed her till she was 1.5 years old. Since then, I’ve dried up.

Yesterday when I was showering, I squeezed my boob a little bit and it looked like colostrum leaking out. Same thing this morning too.

Has this happened to anyone else before? Did you get a positive test also?
