No period?

AF is officially a week late. I thought I got a Vvfl on a test at the beginning of the week but they’ve been negative since. Nausea and vomiting got me yesterday and I’ve been so tired. Nipples are so sensitive and I’m constipated.

What’s the latest you can get a positive test? I will say my cycles have been wacky these past few months.

I don’t track ovulation
