Late period, negative HPT, nausea!

nerdygirl

So according to this app, my period is almost a week late!

I took a hpt & came out negative. I am having BAD nausea... cramps that come & go & they can be bad at times. & sore nipples. But no AF!

I’m sooooo sick to my stomach.

What should I do? Take another hpt? Or am I having just a late period (cycle)?
