Confused on so many levels.

Hubby and I are TTC. My period was supposed to start on 2/18; I’ve missed it entirely. Took two pregnancy tests (2/19 and 2/22) and both were negative. I’m trying to not get my hopes up, but I’ve also never missed a period before...has anybody ever had something like this happen?!

Also...I can’t figure out how to edit my period within the app to say I missed it. It says “period late” and grayed out the boxes, but I can’t update it to then see when the next one supposedly should start. Help, please!!!
