colostrum at 13 DPO

I would I guess be 13 dpo, I am not entirely certain. I've taken 2 test, and both we what I think negative or faulty test. right I after I dipped it in urine there was what looked like and indent line before the control line even had been touched. I couldn't really tell if it had color, lol it was giving me line eye. I also started spotting yesterday, just very very light pink/peachy color. And this morning it was mire of a brown and its only when I wipe well a couple hours after the test I got this weird dull pain on the bottom of my left boob and I went to kinda massage it and white liquid came out of my nipple and its not alot just a drop or so, and even still If i push on my nipple it still comes out. I have never had any children, I was pregnant 2 years ago, but miscarried at 10 weeks. I have never had this happen before. has any one every had this happen this early on or ads an early pregnancy symptom?
