Period is 1-2 days late but negative tests!!!

Dee • TTC our first precious little bundle of joy, July will be 6 months of trying 💕
I was expecting my period on the 28th October, and Glow predicted my period to start on the 30th October (today). 
I have not had my AF yet, and tests are negative so far although I didn't take a test this morning. 
Can tests be negative at this point? Or should it be positive by now if I am pregnant? 
Have been trying for 11months so fingers crossed!!! 🙈🙂 
Any help you can give would be great!!!! 💜
