16days late with negative results/ 😟

Angelina

I need your help, as per Glow my AF was scheduled to appear on 10/28/18 which usually last 5 days on a 28 cycle... I am now 16 days late and went to dr today and UA came back negative as well.. I have done 5 pregnancy test and all negative.. Again im usually never late but I’m a little concerned because I have no symptoms.. I’m also a little nervous because I’ve read up on how at my age 41 I have a very slight chance of conceiving and I’ve already read about cervical cancer and not sure what to think.. I go back this Wednesday for PAP.. Has this happened to anyone or have any idea in what might be going on with my body??
