False positive?

Da

So I got two positive test from two different brands and two different dyes (pink and blue) but my blood results came back as 0 hcg.

I took the test because my period was being really weird it was more pink and light then how it use to be but I’m breastfeeding so that could possibly be why.

I had my daughter 10wks ago so it’s not left over hcg that the tests picked up. Could I really have gotten 2 false positives though from two different test?
