Late period.

This is my first time posting on here but I'm TTC I'm 4 days late and I've been experiencing nausea, boob tenderness and mood swings. I've also been sleeping a lot. My cycle is based on a 24 day. My period has been normal except this month. I was on bc for 3 years but got off of it 5 months ago. I took a pregnancy test yesterday and it came back negative. Do I wait until the week late mark ? What should I do ?
