Ummmm....

So. I’m worried, my period is 6 days late according to the glow app .

I had unprotected sex on 12/12 and my period came on 12/13. Now here we are in January and I have no period yet, every month so far it has been coming around the 15th-17th , but last month it jumped up a few days as I mentioned above. I’m a bit on the stressed side, I wonder if I should wait another week and then take another test.
