normal or ?

Okay, so I'm currently 18 weeks + 2 days prego and this is my second pregnancy. My first ended in a miscarriage at 6 weeks. So, before my BFP, I was leaking colostrum which freaked me out because that had never happened to me before. Also, AF had just left like a few weeks prior. A couple days later, I tested an I got a vfl. A day after that, I went to Planned Parenthood to retest and it was a positive and they said I was 3 weeks and 3 days pregnant. Is it normal to leak colostrum that early ? Because I've been told colostrum comes in at like 3 or 4 months prego. Also, I still leak colostrum everyday.
