No period and negative test

Christina

My period was supposed to be here December 31st and up until now there is no signs that I will be having it and no signs that I am pregnant, also took PT twice now ( 2 different days ) I have been off birth control since September and I am so anxious that I don’t get a positive result when we always time it on my ovulation days. It was different 4 years ago with my first born, I was off brith control for a month and got pregnant the next. It is killing me that I can’t get pregnant anymore, not sure if it is that I am too old and not ovulating as often anymore (I am 35 btw) should I go see my OB.
