Low hormone levels and Implantation bleeding questions.

Does any other mama on here have low hormone levels during their whole pregnancy?
I had it with my DD and I am beginning to have it this time. I'm 7 weeks today but I still can't get a positive pee test (got a positive blood test though). I was 15 weeks with my DD before I could pee on a stick and get a positive.

Also with my implantation bleeding with my DD , I bled really bad for 2 days, then spotted for a week and with this one I spotted for a week then bled bad for 2 days. Anyone else have this problem?
