Hormone imbalance, miscarriage, or pregnant ?

So in the beginning of feb, I started to feel absolutely exhausted and nauseous no matter what I did, I also was getting sharp pains in my right side. A couple weeks went by and I knew my period was coming up and I was extremely moody and my boobs hurt quite a bit. March 14th I started spotting bright pink and thought I’d started Aunt Flo, it was shorter and lighter than my normal period. I thought everything was fine because hey I started but last night, my boyfriend was playing with my breast and I started leaking colostrum. I’ve never had that happen before so I took a test this morning and it was negative. I’m planning on getting a blood test but I was hoping someone might have some advice?

Tl;dr

I’m lactating and I don’t believe I’m pregnant, what should I do?
