How long should I wait?

Rebecca

So my period is 8 days past due. I am pretty scheduled about this and have only ever gone 3 days late before.

I took a pregnancy test when I was at 6 days late and it read “not pregnant “, my question is how many more days should I wait before taking another test? I am trying not to get my hopes up since we have been TTC for 3 years.

Thanks.
