No, not necessarily. I took a pregnancy test the day I was due to get my period, and it came out negative. I waited another 2-3 days when my period still didn't come, and it was a faint positive.
I would give it another week just to make sure that there is the appropriate level of that hormone that shows up on the pregnancy test because if it’s not enough, it’s gonna be negative
I'd give it one more week and then test first thing in the morning
