Three weeks ago I missed a pill by accident & didn't thinks nothing of it & just took another one the next day

On Sunday I decided to stop taking the pill & get my period... But my period still hasn't come

The symptoms I've been having are:

-constantly hungry
-white vaginal discharge
-headaches
-very fatigue
-a little weight gain
&
-a stuffy/blocked nose

Am I pregnant ?

Please help !
