Late period, Neg. Preg. Test. No symptoms!

Okay, normally I wouldn’t post but seeing as though I’m coming up on day four of my period being late, I’m kinda getting curious....

Okay last period was Nov. 30th- Dec.2nd

They are pretty regular give or take 1 day or so. But I was “supposedly” fertile according to my app during the 12-17th of Dec. I had sex on the 15th. Unprotected. Which is fine. I mean we are trying for a baby.

So my next period was supposed to start on the 31st of Dec. NEVER CAME! Still hasn’t came! I have tested and the tests are all NEGATIVE! Like stark white negative. And I have NO symptoms of my period about to start. I do have egg EWCM. (Egg White Cervical Mucus.) idk what the crap is happening, just worried.....

EDIT————- I should add.... my Wedding was Dec 15th so basically the whole first 2 weeks of dec I was SUPERRRRRRR NERVOUS AND STRESSED!
