Confused

i got 3 positive tests and one clear blue digital that said pregnant 1-2 weeks last weekend then Tuesday I started spotting brown/pink blood no cramps or clots took a home test next day in the morning while bleeding and it was negative i went to the hospital the same day for a blood test I got my results back Friday and they said borderline?? Hcg levels rising

anybody shed any light if I am pregnant still or not??

would the blood spotting affect the result??

thankyou
