Is it possible to have both parents with o positive bloodtype, but their child have o negative blood type?

Yes: The rh factor is inherited through separate genetic means from the blood type. The rh factor is a dominant gene, meaning only one gene is needed to cause expression of the factor.

Blood test says my blood type is O Positive but on the part where is says Rh factor it says negative. How does that make sense? Mean something else?

It doesn't: It doesn't really, but here's what probably happened: If you're pregnant and getting prenatal labs, in RH negative patients who've had a previous pregnancy it's typical to test for RH factor antibody (an immune response against RH+ blood).
