Late by a month

Jen
Hello ladies! I need some advice. I have missed my period last month, last period was in December middle of the month and very short when I'm normally 5-7 days I was only 3 in December. 
I have taken several test and they are all negative!!!! My apps keep moving my period days later when I'm entering in that I haven't started. Should I call my doctor? Should I wait it out and see?? My symptoms are--sore breast, kind of tingly more than sore; I have these weird tingly sensations in my stomach/lower abdomen. Are these normal? I'm so confused and I think I'm driving my dear husband crazy. 
Any help is appreciated! Thank you!!!!
