Pregnancy Wonder.

How long should I wait to get a blood test? Cuz it would have been 5 weeks since my last actual period.

I was supposed to have my period last week but it was late and came extremely light and pinker than usual and a pad was too much for how little there was and lasted 2 days instead of 5 it was slight heavier than spotting but still very little. I took a pregnancy test 6 days ago before the “spotting” and it said negative but with slight nausea, frequent urination still etc Im not sure if I could be still. And I don’t want to go to early for a blood test.
