Pregnant or period late??

Question

Hey ladies so I'm in need of some advice.
My last period was sept 12, it was very normal. I was supposed to get it again oct 14. Normally I am a few days late but it always come, this time it never did. I took a pregnancy test on the 18th of oct but it was negative. Now today is the 25th and it still hasn't come. I was thinking about going to the doctor if it still hasn't came by Tuesday. 
No sure if it could I'm pregnant but to soon to tell or I'm just way late?! 
Any advice would be helpful

Answer

Wait another week you could just be late. I've been two weeks late. 
Test again too btw, just not a digital yet.
