2 weeks late and freaking out

Hi, I need advice PLEASE! I am 27 years old and I was on the pill for about 10 years due to health issues I had to get off it months ago and I haven't been late since I got off the pill. I am currently 2 weeks late and I'm still getting negative results from the pee stick. I know stress can be a factor but I've been way more stressed out before. I have all the symptoms but they can also be period symptoms. Help, please
